Harmonic and microlocal analysis in PDEs
16 dec 2024 - 20 dec 2024 • Parkville/Melbourne, Australie
Résumé:
The mathematical theory of partial differential equations (PDE) draws on many parts of analysis, including functional analysis, semigroup theory, calculus of variations, and others. Two of the most significant branches of mathematical analysis that have contributed to PDE theory are harmonic analysis and microlocal analysis. This research program aims to foster and further develop this synergy between harmonic and microlocal analysis. It will bring together international and Australian researchers who are, in one way or another, at or close to the interface of harmonic and microlocal analysis, to listen to the latest developments and work together to build new collaborations that will enrich both these areas of analysis, as well as PDE theory, in the future. This research program will be the final event in the 2024 Special Year in Harmonic Analysis at the Australian National University.

RESEARCH IN RESIDENCE — Dispersion correction for the convected Helmholtz equation
20 jan 2025 - 24 jan 2025 • CIRM (Marseille Luminy), France
Organisateur:
CIRM – Centre International de Rencontres Mathématiques
Résumé:
Solving time-harmonic wave equations with iterative methods is very challenging because they combine multiple difficulties like e.g. highly oscillatory solutions and complex non-Hermitian and indefinite discrete operators. In addition, the wave number associated to the numerical solution is different from the one of the exact solution thus leading to so-called numerical dispersion which requires very fine mesh to be controlled. There exists numerical schemes designed to reduce the dispersion error where the most used technique to build them relies on stencils involving free parameters that are next obtained by numerically minimizing the dispersion error. In the past few years, we develop an alternative approach called asymptotic dispersion correction. The latter is based on the introduction of a perturbation of the wavenumber (the shift) in the numerical scheme. We then explicitly compute the shift that minimizes the dispersion error for small enough meshsize. In addition, we show that our method can be applied to any finite difference scheme and reduces the relative error. We emphasize that most of works dealing with dispersion reducing methods consider the Helmholtz equation. The goal of the Research in Residence is to extend the asymptotic dispersion correction to the convected Helmholtz equation that can be used to model time-harmonic wave propagation in a moving flow.

Dispersive Integrable Equations: Pathfinders in Infinite-Dimensional Hamiltonian Systems
28 avr 2025 - 02 mai 2025 • CIRM (Marseille Luminy), France
Organisateur:
CIRM – Centre International de Rencontres Mathématiques
Résumé:
The conference, in advance of a thematic program planned for IHP in 2026, addresses the key role played by completely integrable systems as models for wave phenomena in myriad physical settings such as surface water waves and internal waves, quantum excitations in Bose-Einstein condensates, plasma oscillations, optical fiber telecommunication systems, and solid-state physics. The principal objectives of the CIRM conference are to focus specifically on soliton gases, explicit formulas, and asymptotic behavior in integrable models, and to highlight corresponding novel results and new progress on several previously impenetrable fronts.

QUASIWEEKEND III
09 jui 2025 - 13 jui 2025 • Helsinki, Finlande
Organisateur:
University of Helsinki
Résumé:
Conference Quasiweekend III - Twenty years on collects together experts, from all fields of mathematics, using quasiconformal methods, especially in complex dynamics, geometric function theory, geometric group theory, analysis on metric spaces. Previous conferences in this series, Quasiweekend and Quasiweekend II – Ten years after, took place in 2005 and 2015, respectively, in Helsinki. With Quasiweekend III we celebrate mathematical legacy of Juha Heinonen -- initiator of this conference series -- in the broad field of quasiconformal analysis.

RESEARCH IN RESIDENCE — Elliptic and parabolic equations originating from real world problems
29 sep 2025 - 10 oct 2025 • CIRM (Marseille Luminy), France
Organisateur:
CIRM – Centre International de Rencontres Mathématiques
Résumé:
The abstract foundation of the book concerning functional analysis, special issues on Sobolev type function scales, and elliptic and parabolic regularity in case of non-smooth data, is already solid. However, the culminating last part of the book is still under discussion and editing. There, it is intended, using the theory established before, to give a condensed and unified treatment of wellposedness for several real-world problems, namely the thermistor problem, the Keller-Segel chemotaxis model, and the macroscopic semiconductor equations (Van Roosbroeck system) in case of Avalanche generation, all for the case of non-smooth spatial domains. These problems were open for decades and solved only recently by the authors and collaborators in journal articles.
