Title: Scattering and energy cascade for the Klein-Gordon-Zakharov system in two dimensions
Abstract: We study the Klein-Gordon–Zakharov system in two spatial dimensions, an important model in plasma physics. For small, smooth, and spatially localized initial data, we establish the global existence of solutions and characterize their sharp long-time behavior, including sharp time decay, scattering, and growth of Sobolev norms. The major obstacles are lack of symmetry and weak decay of the solution in two dimensions. To overcome these, we introduce a novel nonlinear transformation of the wave component and reinterpret the nonlinear coupling as a perturbation of the mass term in the Klein-Gordon equation. The proof employs a combination of physical space and frequency space methods.

Title: Generalised e-Harish-Chandra theory and generic weights for finite reductive groups
Abstract: Harish-Chandra theory is a significant tool in Lie theory, such as in the representation theory of Lie groups, Lie algebras and finite reductive groups. In this talk, we will discuss a generalisation of e-cuspidality in the generalised e-Harish-Chandra theory of finite reductive groups, and define the generic weights, which play an analogous role as the weights defined by Alperin in the investigation of the inductive Alperin weight condition for simple groups of Lie type at most good primes. Based on recent joint work with Gunter Malle and Jiping Zhang.
