We still lack, however, an effective or constructive understanding of three-dimensional hyperbolic geometry, and more generally, 3-manifold topology. For example, a closed hyperbolic 3- manifold admits a finite cover which fibers over the circle, but can one construct such a cover from a presentation of the fundamental group? Can one implement an algorithm -- perhaps with the help of preexisting software such as SnapPea -- to obtain such a cover? While much work remains, both computation and theory have progressed. Fast algorithms have been developed for running computations in the mapping class group and other finitely generated groups, as well as for recognizing certain types 3-manifolds and knot and link complements up to homeomorphism. These have been supplemented by a new wave of constructive theorems which explicitly relate the algebra of the fundamental group of a hyperbolic 3-manifold to its geometry, and to the geometry of various simplicial complexes, such as the curve complex. This ICERM workshop will focus on such advances, as well as on the development of new algorithms and extension of algorithmic techniques to the study of free groups. The workshop aims to bring together researchers from a broad range of related fields to work towards a more effective and quantitative understanding of 3-manifold topology, geometric group theory, and hyperbolic geometry. ------------------------------------------------------- From: Kati Wolter [log in to unmask] Date: November 05, 2015 Subject: Mixed Integer Programming (MIP 2016), USA, May 2016 We are pleased to announce that the 2016 workshop in Mixed Integer Programming (MIP 2016) will be held May 23rd-26th at the University of Miami, in Coral Gables, FL.

Registration: February 15, 2016 Submission of extended abstracts: March 1, 2016 Notification of acceptance: April 1, 2016 ------------------------------------------------------- From: ICERM [log in to unmask] Date: October 29, 2015 Subject: Algorithmic Coding Theory, USA, Jun 2016 Algorithmic Coding Theory (June 13 - 17, 2016) https://icerm.brown.edu/topical_workshops/tw16-3-act/ In the theory of error correcting codes, a sender (Alice) wants to send a message to a receiver (Bob), over a noisy channel. Strategies for Alice and Bob have been studied since the works of Shannon and Hamming from the late 1940's, from many different communities. Coding theory is a fundamental solution to challenges that arise in communication, storage, cryptography, and others; as the world changes, our challenges in these areas change, and the scenario changes for Alice and Bob. Fueled by these new scenarios, coding theory remains a rapidly advancing area of research. One trend in many of these new scenarios in coding theory is the need for algorithmic solutions. For many problems in coding theory, it is possible to come up with nearly optimal solutions (information-theoretically speaking) which are likely very hard for Alice and Bob to actually implement. The goal of algorithmic coding theory is to design solutions which are not only combinatorially good, but are also computationally efficient. The goal of this workshop is to bring together researchers from several different communities -- applied math, theoretical computer science, communications and electrical engineering -- to focus on a few quickly- moving topics in algorithmic coding theory. Topics will include: Polar codes; Codes for interactive communication; Local decoding and coding for distributed storage; Non-malleable codes. ------------------------------------------------------- From: Marco Bittencourt [log in to unmask] Date: October 30, 2015 Subject: ICOSAHOM 2016, Brazil Jun 2016 ICOSAHOM'16, International Conference on Spectral and High-Order Methods 2016 June 27- July 01 2016, Rio de Janeiro, BRAZIL http://www.icosahom2016.org/ Minisymposium Proposal: Submission Deadline, December 15 2015 The 11th International Conference on Spectral and High-Order Methods, will be hosted by the University of Campinas and Pontifical University of Rio de Janeiro in city of Rio de Janeiro, Brazil on June 27 - July 01, 2016.

This separation is, however, completely artificial; it is impossible to “find” a mathematical idea without explaining it. Exploration and exposition are two sides of the same coin. One striking example of this is the epochal work of William Thurston; often his theorems were accompanied by pictures, and computer programs, illustrating the underlying ideas. The goal of this conference is to bring together mathematicians from a range of fields, and practitioners from the digital arts (animation, 3D printing, laser cutting, CNC routing, virtual reality, computer games, etc). The attendees will share their expertise in mathematics and with the procedural tools used to illustrate mathematics. In addition to talks in the traditional style, we plan to hold several workshops to train attendees about a variety of digital media, in particular 3D printing. ------------------------------------------------------- From: Amos Lawless [log in to unmask] Date: November 06, 2015 Subject: Data Assimilation, UK, Jul 2016 It is our pleasure to announce the first call for the 5th International Symposium on Data Assimilation (ISDA) 2016 to take place on July 18-22 at the University of Reading, U.K., home to the Data Assimilation Research Centre. The ISDA 2016, follows the success of the ISDA 2015 held at the RIKEN Advanced Institute for Computational Science (AICS), Kobe, Japan and previous symposia held in Germany (LMU (2014), DWD (2012-2013)). The symposium will bring together about 150 researchers and consist of invited talks from leading scientists, short oral presentations with extended discussion, and extended poster sessions. The deadline for abstract submission is the 5th February 2016. Instructions for abstract submission and further information can be found on the symposium website: http://www.isda2016.net ------------------------------------------------------- From: ICERM [log in to unmask] Date: October 29, 2015 Subject: Stochastic numerical algorithms, USA, Jul 2016 Stochastic numerical algorithms, multiscale modeling and high- dimensional data analytics (July 18 — 22, 2016) https://icerm.brown.edu/topical_workshops/tw16-5-sna/ This workshop is concerned with sampling challenges, modeling and simulation for data-rich applications in high dimensions. It brings together mathematicians, statisticians and computational scientists to explore the interplay between computational applied mathematics and data science. On the agenda will be novel developments in the study of complex phenomena based on data-analytic techniques, such as efficient calculation of ergodic (long term) averages and statistical inference under a wide range of geometric, physical and analytical constraints. In applied mathematics and computational science, in particular in molecular modeling, image analysis and geosciences, among others, many objects of interest are high-dimensional and stochastic, and a wide variety of techniques have been developed for sampling and approximating the quantities of interest. Similar issues arise in the area of data science and statistical modeling, where learning problems in the presence of high-dimensional data require efficient computational algorithms for sampling and approximation. The workshop will focus on recent advances in the design of rigorous discrete-dynamics based sampling approaches, algorithms development for large-scale data analysis and stochastic dynamical systems, scalable and rigorous numerical methods for stochastic differential equations and sampling from high-dimensional distributions, and exploitation of low- dimensional structures in high-dimensional data and stochastic dynamical systems for model reduction and efficient Monte-Carlo schemes. The meeting will foster the interchange and deployment of the latest methodologies for sampling and approximation. ------------------------------------------------------- From: Pamela Bye [log in to unmask] Date: October 30, 2015 Subject: Turbulence, Waves and Mixing, UK, Jul 2016 In Honour of Lord Julian Hunt’s 75th Birthday Wednesday 6 – Friday 8 July 2016 King’s College Cambridge, UK http://www.ima.org.uk/conferences/conferences_calendar/turbulencewavesmixing.ht ml The theme of this conference is to discuss, with review lectures and contributed papers, the ongoing developments of research in ‘turbulence, waves and mixing’ and their applications in industry, environment and geo/astro and mathematical physics. Our understanding and the fundamental questions about turbulence and mixing have kept developing since O. Reynolds and Boussinesq made turbulence a subject in 1880s. Pioneers such as Taylor, Prandtl, Richardson (of King’s College), Kolmogorov (his paper was published 75 years ago!) and others developed the dynamical and statistical approaches. Conceptual developments and advances in practical modelling and prediction during the past 75 years, have benefitted from 3-dimensional measurement techniques and computer simulations at very high Reynolds number (>10 5), so that for example patterns, organised eddy structures, particle trajectories and conditional analysis can be better quantified and applied in practice. Papers at the conference cover a wide swath of topics from large scale instabilities that generate turbulence to small scale eddies that dissipates turbulence. Research into the interactions between turbulence and waves in engineering and geophysics, which are equally interesting and controversial, are also included in the conference, such as advances in water waves, KdV, solitons, Tsunami and Air-Sea interactions. Papers will be accepted for the conference based on a 500 word abstract for oral presentation. Abstracts should be submitted by Friday 13 November 2015 to Easychair via https://easychair.org/conferences/? conf=imatwm2016. Please visit the conference webpage in order to download the required template: http://www.ima.org.uk/conferences/conferences_calendar/turbulencewa vesmixing.html Successful authors will be notified in January 2016 and invited to submit a paper for inclusion in the conference proceedings 11 March 2016. ------------------------------------------------------- From: ICERM [log in to unmask] Date: October 29, 2015 Subject: Cycles on Moduli Spaces, USA, Aug 2016 Cycles on Moduli Spaces, Geometric Invariant Theory, and Dynamics (August 1 – 5, 2016) https://icerm.brown.edu/topical_workshops/tw16-4-ms/ A moduli space parameterizes geometric objects with alike structures and encodes in itself the geometry of all possible families of such objects. This workshop will focus on three aspects of moduli spaces: Cycles, Geometric Invariant Theory, and Dynamics. One of our main goals is to synthesize the recent progress on moduli of abelian differentials on algebraic curves motivated by dynamics and in the GIT constructions of related moduli spaces, with the view towards better understanding of geometric cycles on these moduli spaces. In many cases, computer programming and experiments are important tools to discover new phenomena, both in dynamics and in the study of cycles on moduli spaces. Hence many talks will emphasize computational and experimental aspects of these fields and the workshop will feature a computational problem session whose goal is to disseminate computational techniques and problems to a wider body of researchers. ------------------------------------------------------- From: Alex Pothen [log in to unmask] Date: October 30, 2015 Subject: Faculty Positions, Computer Science, Purdue Univ The Department of Computer Science at Purdue University is in a phase of significant growth.
