Il 10 e 11 Dicembre 2025, per il ciclo “Crossings - Math Seminars”, Eugenia Malinnikova (Stanford University) terrà i seguenti interventi:
#1
Math Forum: Landis Conjecture in dimension 2: introduction
Abstract: We will discuss bounded solutions to the Schrodinger equation with bounded potential. It was conjectured by Landis in 1960s that such solutions cannot decay faster than exponentially. In the 1990s, Meshkov constructed a counterexample for the case of complex valued potential. We will survey the history of the problem and describe a recent work with Logunov, Nazarov, and Nadirashvili, which proves the original Landis conjecture in dimension two for the case of real-valued potentials.
Data e ora: Mercoledì 10 Dicembre, ore 16:00
Luogo: Aula U6-29 (Edificio U6 - Piazza dell'Ateneo Nuovo 1, Milano - Università degli Studi di Milano-Bicocca)
Al termine del seminario seguirà un aperitivo
#2
Technical Seminar: Landis Conjecture in dimension 2: technical details
Abstract: In this second lecture, we will provide the details of the construction in the resolution of the Landis conjecture in dimension two. Specifically, we will explain how the quasiconformal mappings are used to reduce the problem to one concerning harmonic functions and present a solution to that reformulated problem.
Data e ora: Giovedì 11 Dicembre, ore 15:45
Luogo: Aula U7-04 (Edificio U7 - Via Bicocca degli Arcimboldi 8, Milano - Università degli Studi di Milano-Bicocca)
