Rump [log in to unmask] Date: February 09, 2015 Subject: INTLAB Version 9 for Matlab and Octave Version 9 of INTLAB, the Matlab toolbox for Reliable Computing, is now available for Matlab and Octave on http://www.ti3.tuhh.de/intlab Given a numerical problem, INTLAB delivers verified bounds for the solution together with a proof of existence and possibly uniqueness. Correctness includes all procedural, possible discretization and rounding errors as well as I/O. The input data may be afflicted with tolerances. INTLAB comprises of several separate toolboxes including automatic differentiation (gradients, Hessians, Taylor expansion, slopes), affine arithmetic etc. together with problem solving routines for linear/nonlinear dense/sparse systems, (generalized) eigenvalue problems etc. For Octave the INTLAB package is self-contained including Octave Version 3.8.2. ------------------------------------------------------- From: Institute for Computational and Experimental Research in Mathematics [log in to unmask] Date: February 04, 2015 Subject: Mathematics of Lattices and Cybersecurity, USA, Apr 2015 Mathematics of Lattices and Cybersecurity April 21-24, 2015 ICERM, Brown University, USA http://icerm.brown.edu/topical_workshops/tw15-7-mlc/ Lattices are abstractly very simple objects, yet their concrete realizations contain beautifully intricate problems that are stubbornly difficult even in low dimensions. For example, our present day understandings of densest lattice packings and reduction theory are still plagued with large gaps. In the 1970's and 1980's lattices entered the world of cryptography as tools used to break certain crypto systems, particularly those based on the subset sum problem, and since the 1990's they have become increasingly important in the building of other types of crypto systems (thanks to the difficulty in the underlying mathematics). Their significance has recently been bolstered by average-case complexity bounds and their present resistance to quantum computing attacks. Currently the theory of lattices is a lively research topic among mathematicians, computer scientists, and experts in cybersecurity. However, to this date, there has been little to no interaction between these communities. The goal of this workshop is to stimulate activity between these different groups interested in lattice problems. Topics to be covered include, but are not restricted to, recent results on densest lattice packings, the geometry of lattice moduli space and its connections with automorphic forms and algebraic number theory, cryptographic applications of lattices, and the state of the art of lattice reduction in high dimensions. ------------------------------------------------------- From: Roumen Anguelov [log in to unmask] Date: February 06, 2015 Subject: BIOMATH Conference, Bulgaria, Jun 2015 2015-06-14 - 2015-06-19 BIOMATH 2015: International Conference on Mathematical Methods and Models in Biosciences, University Centre Bachinovo, South-West University, Blagoevgrad, Bulgaria The conference is devoted to recent research in life sciences based on applications of mathematics as well as mathematics applied to or motivated by biological studies.
