Meetings/Workshops on Algebra in the United Kingdom

Aran Tattar and Nicholas Williams, University of Leicester

Categorifications are category-theoretic analogues of mathematical phenomena. This process can engender mathematical progress by allowing problems to be attacked with new techniques and theory that exist in a categorical setting. Categorification does not in general have a strict definition, and can refer to approaches in a range of different areas. This online conference aims to bring together postgraduate and early career researchers interested in a wide variety of categorifications. We encourage abstracts on a broad range of subjects, for example, categorification of cluster algebras, of quantum groups; n-categorical approaches, monoidal categorifications.

The aim of this conference is to bring together experts and young researchers from various fields and communities in mathematics related to operator semigroups and linear evolution equations. The conference will also celebrate Charles Batty’s ongoing outstanding contributions to the theory of operator semigroups, C*-algebras and their relations to other areas of analysis. We expect there to be around 60 participants in the conference, about half of them early career researchers (Ph.D. students and postdocs).

The International Workshop on Operator Theory and its Applications meets annually to bring together mathematicians and engineers who work in functional analysis and its application to related areas.

Analysis,    Applied Mathematics (in general)

Clay Mathematics Institute (CMI)

Spectral geometry, calculus of variations, and elliptic PDEs are a central part of modern analysis and geometric analysis. At the same time, these have important applications in other sciences, in particular mathematical physics. This workshop aims to bring together leading experts in these fields to discuss the main developments and open questions. The main research themes of the workshop include shape optimisation and sharp functional inequalities, Robin boundary value problems, Steklov eigenvalue problems, and properties of eigenfunctions and solutions to elliptic PDEs.

Calculus, Differential Equations and Integration,    Geometry and Topology

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. This Conference has been organised in cooperation with the Society for Industrial and Applied Mathematics (SIAM).
