Cangiani, Z. Dong, E.H. Georgoulis, and P. Houston. hp-Version Discontinuous Galerkin Methods on Polygonal and Polyhedral Meshes. SpringerBriefs in Mathematics, December 2017 http://www.springer.com/gb/book/9783319676715 Over the last few decades discontinuous Galerkin finite element methods (DGFEMs) have been witnessed tremendous interest as a computational framework for the numerical solution of partial differential equations. Their success is due to their extreme versatility in the design of the underlying meshes and local basis functions, while retaining key features of both (classical) finite element and finite volume methods. Somewhat surprisingly, DGFEMs on general tessellations consisting of polygonal (in 2D) or polyhedral (in 3D) element shapes have received little attention within the literature, despite the potential computational advantages. This volume introduces the basic principles of hp-version (i.e., locally varying mesh-size and polynomial order) DGFEMs over meshes consisting of polygonal or polyhedral element shapes, presents their error analysis, and includes an extensive collection of numerical experiments. The extreme flexibility provided by the locally variable element-shapes, element-sizes, and element-orders is shown to deliver substantial computational gains in several practical scenarios. ------------------------------------------------------- From: Marco Donatelli [log in to unmask] Date: December 13, 2017 Subject: Inverse Problems in Imaging, Italy, May-Jul 2018 The Organizing Committee is pleased to announce the INDAM intensive bimester program "Computational Methods for Inverse Problems in Imaging", May 21 - July 20, 2018, University of Insubria, Como, Italy.

The meeting is organised in cooperation with SIAM, whose members will receive the IMA members' registration rate. The success of modern codes for large-scale optimization is heavily dependent on the use of effective tools of numerical linear algebra. On the other hand, many problems in numerical linear algebra lead to linear, nonlinear or semidefinite optimization problems. The purpose of the conference is to bring together researchers from both communities and to find and communicate points and topics of common interest. Conference topics include any subject that could be of interest to both communities, such as: Direct and iterative methods for large sparse linear systems; Eigenvalue computation and optimization; Large-scale nonlinear and semidefinite programming; Effect of round-off errors, stopping criteria, embedded iterative procedures; Optimization issues for matrix polynomials; Fast matrix computations; Compressed/sparse sensing; PDE-constrained optimization; Distributed computing and optimization; and Applications and real time optimization. Mini-symposium proposals and contributed talks are invited on all aspects of numerical linear algebra and optimization. Mini-symposium proposals should be submitted to [log in to unmask] by 31 January 2018. A mini-symposium consists of up to four speakers. For emerging topics the mini-symposium can be extended to at most two sessions on a single topic (maximum eight speakers). Organisers will be advised of acceptance by 12 February 2018. Contributed talks and mini- symposia talks will be accepted on the basis of a one page extended abstract which should be submitted by 28 February 2018 online at https://my.ima.org.uk. Authors will be advised of acceptance by 31 March 2018. A book of abstracts will be made available to delegates at the conference. ------------------------------------------------------- From: Roland Herzog [log in to unmask] Date: December 14, 2017 Subject: Tenure-Track Postdoc Position, TU Chemnitz, Germany The faculty of Mathematics at TU Chemnitz is opening a two-year postdoc position.
