Título: Magic Functions
Palestrante: Felipe Gonçalves (IMPA)
Data: 19/10/2022
Horário: 12:00h
Local: Sala C-116
Resumo: We will talk about some of the challenging problems in different areas of mathematics that were solved by constructing certain "magic" functions with constraints on physical and/or frequency space (we shall focus slightly on the bandlimited case). The talk will be based entirely on examples, one of which is the sphere packing problem (its solution awarded the Fields medal to the Ukrainian female mathematician M. Viazovska).
