        "description":"Focusing nonlinear Schr\u00f6dinger equation serves as a universal model for the amplitude of a wave packet in a general one-dimensional weakly-nonlinear and strongly-dispersive setting that includes water waves and nonlinear optics as special cases. Rogue waves of infinite order are a novel family of solutions of the focusing nonlinear Schr\u00f6dinger equation that emerge universally in a particular asymptotic regime involving a large-amplitude and near-field limit of a broad class of solutions of the same equation. In this talk, we will present several recent results on the emergence of these special solutions along with their interesting asymptotic and exact properties. Notably, these solutions exhibit anomalously slow temporal decay and are connected to the third Painlev\u00e9 equation. Finally, we will extend the emergence of rogue waves of infinite order to the first several flows of the AKNS hierarchy\u2014allowing for arbitrarily many simultaneous flows\u2014and report on recent work regarding their space-time asymptotic behavior under a general flow from the hierarchy.",

In joint work with Patrick Daniels, Pol van Hoften, and Mingjia Zhang, we construct Igusa stacks for all abelian type Shimura data and apply them to the study of $\\ell$-adic cohomology of Shimura varieties. I will discuss the geometric ingredients that go into the construction as well as how it naturally fits into Fargues--Scholze's framework of categorical local Langlands",
