Well-posedness and asymptotic behavior of one-dimensional wave equations with a set-valued boundary condition


Speaker: Guilherme Mazanti, INRIA, France



Abstract of the talk

Poster


Short bio: After his Engineering degrees from the São Carlos School of Engineering, University of São Paulo, Brazil, and from École Polytechnique, France, Guilherme Mazanti obtained his Master's degree on Applied Mathematics at École Polytechnique in 2013 and his Ph.D. on Applied Mathematics also at École Polytechnique, University Paris–Saclay, in 2016, after defending his thesis on the stability and control of linear switched systems in finite and infinite dimensions. From September 2016 until August 2019, he was a postdoctoral fellow at the Laboratory of Mathematics of Orsay, University of Paris-Sud, working mostly on the analysis of minimal-time mean field games. From September 2019 until September, 2020, he was a postdoctoral researcher in a joint project of the Polytechnic Institute of Applied Sciences (IPSA), of Inria research center Saclay – Île-de-France, and of CentraleSupélec's Laboratory of Signals and Systems (L2S), working on the stabilization of time-delay systems. He is currently a researcher at Inria, at the Saclay - Île-de-France research center, and part of the team "Dynamical Interconnected Systems in Complex Environments" (DISCO). He is also a member of the Laboratory of Signals and Systems (L2S) at CentraleSupélec. His main research interest is on control theory, with several research topics lying between applied mathematics and engineering, such as stabilization and asymptotic behavior of time-delay systems, control and stabilization of hyperbolic PDEs, mean field games, and switched systems.

Abstract of the talk


Poster


Short bio: His interests are in mathematical analysis and dynamical systems. His thesis has centered around: semigroups of linear operators and their adjoints in the context of various classes of delay differential equations, and applications to the analysis of existence, stability, and bifurcation of relatively simple invariants of parameter-dependent nonlinear systems, such as equilibria and periodic orbits.

Global and generic dynamics for semiflows strongly monotone with respect to high-rank cones: theory and application to generic periodicity in high dimensional epidemic models


Speaker: Jianhong Wu, York University, Canada.



Abstract of the talk: This talk is based on a series of studies in collaboration with Lirui Feng and Yi Wang, on semiflows on a Banach space X which are strongly monotone with respect to a “cone” C of rank k. Examples of such semiflows including delay differential equations with negative feedback when the initial data is restricted to the subset of functions with sign changes less than a given integer. Other examples including predator-prey systems and epidemic models where the nonlinearity allows the flow to be monotone with respect to a quadratic-cone. High rank cones do not have the convexity in the classical cones. We establish the trichotomy of $omega$-limit sets of pseudo-ordered precompact semi-orbits, and the Poincare-Bendixson type Theorem in the case where k = 2. The generic Poincare-Bendixson Theorem for the case k=2. provides a systematic framework for us to obtain the existence of periodic solutions and convergency to periodicity in high dimensional predator-prey and epidemic systems with unstable interior equilibria.

Short bio: Jianhong Wu is a University Distiguished Research Professor of Mathematics, senior Canada Research Chair in Industrial and Mathematics, and the NSERC/Sanofi Industrial Research Chair in Vaccine Mathematics, Modelling and Manufacturing, at York University, Canada. His research interest includes the qualitative theory of nonlinear systems with applications to population dynamics and infectious disease transmission dynamics, neural computation with applications to high dimensional data clustering.

Abstract of the talk


Short bio: Carlos Kenig is the Louis Block Distinguished Service Professor in the Department of Mathematics at the University of Chicago. Kenig is recognized for his applications of tools and techniques of harmonic analysis to a number of different areas of partial differential equations. In particular, in the last 30 years Kenig has made pioneering contributions to the study of nonlinear dispersive equations, including his recent research on the classification of the long-time behavior of large solutions. Kenig was born in Buenos Aires, Argentina in 1953. He obtained his PhD at the University of Chicago in 1978. After being an instructor at Princeton University and a professor at the University of Minnesota, Kenig returned to the University of Chicago in 1985. Kenig was awarded the Salem Prize in 1984 and the Bocher Prize of the American Mathematical Society in 2008. Kenig received the Solomon Lefschetz medal of the Mathematics Council of the Americas in 2021. He was an invited speaker at the International Congress of Mathematicians in 1986 and 2002 and a plenary speaker in 2010. In 2017 Kenig delivered the American Mathematical Society’s Colloquium lectures. Kenig is a Fellow of the American Academy of Arts and Sciences and of the American Mathematical Society. He is a member of the National Academy of Sciences and a past vice‐president of the American Mathematical Society. Kenig currently serves as the President of the International Mathematical Union for the period 2019­2022.
