Date: 26th of February to 2nd of March, 2018 Place: Kiel University, Kiel, Germany Organizers: Wolfgang Hackbusch, Lars Grasedyck, Steffen Boerm Hierarchical matrices offer an efficient approach to handling non-local operators resulting, e.g., from the discretization of an integral equation or the inversion of a partial differential equation. They rely on a decomposition of a matrix into sub-matrices of low numerical rank that can be represented in factorized form. Using this representation, we can perform operations like the matrix-vector multiplication, matrix multiplication, inversion, factorization, the evaluation of matrix functions, or even the solution of certain matrix equations in almost linear complexity. The winter school is split into two parts: lectures present the fundamental concepts and algorithms, while practical exercises allow the participants to experience the methods first-hand, get acquainted with the open-source library H2Lib (http://www.h2lib.org), and discuss specific questions and applications with experts in the field. Participation is free of charge. Please address questions and registration requests to [log in to unmask] ------------------------------------------------------- From: Mathias J.

The meeting is being held in cooperation with SIAM, and SIAM Activity Groups on Optimization and on Linear Algebra. SIAM 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. ------------------------------------------------------- From: E.

The project will advance a method for calculating energy flow in complex structures developed in Nottingham, the so-called Dynamical Energy Analysis (DEA). The method is used for computing noise and vibration in vehicle structures as well as electromagnetic field distributions in complex cavities. DEA exhibits a rich underlying mathematical structure based on transfer operators originally arising in the theory of chaotic dynamical systems. A good knowledge of computational wave modelling is essential. In addition, a background in more than one of the following areas is highly desirable: short wavelength asymptotic methods, numerical solutions of PDEs, programming, numerical linear algebra, numerical analysis, and functional analysis. This full-time position is available from 1 February 2018 or as soon as possible thereafter and will be offered on a fixed-term contract for a period of thee years. The post is a joint appointment (50:50 split) between UoN and NTU and the person appointed will be based at UoN and NTU campuses. The salary will be 32548 to 34520 (GBP) per annum.
