Accepted Minisymposia

Numerical methods for surface and interface dynamics

Organisers: Buyang Li (Hong Kong Polytechnic University, Hong Kong) and Rong Tang (Hong Kong Polytechnic University, Hong Kong)

Speakers: Fabian Heimann (University College London, UK), Bjorn Stinner (University of Warwick, UK), Vanessa Styles (University of Sussex, UK), Chandrasekhar Venkataraman (University of Sussex, UK), Andrea Bonito (Texas A&M University, USA), Guosheng Fu (University of Notre Dame, USA), Shawn W. Walker (Louisiana State University, USA), Balázs Kovács (University of Paderborn, Germany), Yifei Li (University of Tübingen, Germany), Paola Pozzi (University of Duisburg-Essen, Germany), Bangwei She (Capital Normal University, China), Rong Tang (Hong Kong Polytechnic University, Hong Kong)

Abstract: The dynamics of interface and boundary in partial differential equations (PDEs) are of paramount importance in various applications. Efficient numerical methods and rigorous numerical analysis for solving these PDEs have both theoretical and practical values. This mini-symposium aims to discuss recent advances in numerical methods and applications related to moving surface and interface problems, such as PDEs with moving boundary/interface problems, surface evolution in geometric flows, and fluid-structure interactions, among others.

Advances on nonstandard Galerkin methods - part 1

Organiser: Zhaonan Dong (INRIA Paris)

Speakers: Lina Zhao (City University Hong Kong), Andrea Cangiani (SISSA, Trieste), Andreas Rupp (Saarland University), Guosheng Fu (Notre-Dame University), Geraldine Pichot (INRIA Paris), Scott Congreve (Charles University Prague), Tien Ngoc Tran (University Augsburg), Philip Herbert (University of Sussex), Christian Döding (University of Bonn)

Abstract: In this minisymposium, we aim at gathering researchers working in the field of nonconforming Galerkin methods. Among possible topics of interest, we list: nonconforming finite element methods; immersed Galerkin methods; nonpolynomial based Galerkin methods; cut finite elements; PDE properties-preserving (positivity, conservation, divergence-preserving...) methods. This is part 1 of a series of two minisymposia on nonconforming methods.

Advances on nonstandard Galerkin methods - part 2

Organiser: Lorenzo Mascotto (University of Milano-Bicocca)

Speakers: Ruchi Guo (Sichuan University), Weifeng Qiu (City University Hong Kong), Paul Ledger (Leicester University), Tristan Pryer (Bath University), Simon Lemaire (INRIA Lille), Sara Zahedi (KTH Stokholm), Manolis Georgoulis (National Uni Athens - Heriot-Watt University), Wietse Boon (NORCE Norwegian Research Centre), Philip Lederer (University Hamburg)

Numerical Methods for Mean Field Games

Organisers: Yohance Osborne (Durham University), Iain Smears (University College London) and Harry Wells (University College London)

Speakers: Elisa Calzola (Rome Sapienza), Harry Wells (University College London), Ahmad Zorkot (University of Limoges), E. Carlini (Rome Sapienza), Indranil Chowdhury (Indian Institute of Technology Kanpur), Diogo Gomes (KAUST Saudi Arabia)

Abstract: Mean field games are a system of nonlinear partial differential equations (PDEs) that model Nash equilibria of stochastic differential games involving a large numbers of players. They find applications across many fields, including mathematical biology, engineering, economics, and finance. This minisymposium will present recent developments in the design and analysis of discretisation methods for these problems to address the many numerical challenges encountered, such as structure preservation, first-order systems, nonlocal diffusions, error analysis and convergence rates, and nonsmoothness of the nonlinearities.

Interplay of solvers, discretisations and geometries in the numerical approximation of eigenvalue problems

Organisers: Fleurianne Bertrand (TU Chemnitz) and Philipp Zilk (Universität der Bundeswehr München)

Speakers: Davide Pradovera (KTH Royal Institute of Technology), Tugay Dagli (TU Chemnitz), Arbaz Kahn (Indian Institute of Technology Roorkee), Luca Grubišić (University of Zagreb), Nils Friess (Universität Heidelberg), Henrik Schneider (Universität Duisburg Essen)

Abstract: The numerical approximation of eigenvalue problems for partial differential equations (PDEs) plays a critical role in diverse scientific and engineering applications, such as wave propagation, structural mechanics, and material sciences. This mini-symposium aims to delve into the intricate interplay between solvers, cutting-edge numerical methods, and geometries that influence the accuracy and efficiency of eigenvalue computations.
