Special Group Theory Seminar

Is Being a Higher Rank Arithmetic Group a First Order Property?
Chen Meiri
11:30am|Simonyi Hall 101 and Remote Access

Higher rank arithmetic groups are rigid in many senses. What about the collection consisting of these groups? Are there group theoretic properties which hold only for the groups in this collection? In this talk we will present a conjecture that there...


Members' Colloquium

Fourier Uniqueness and Nonuniqueness Pairs
Mikhail Sodin
2:00pm|Simonyi 101 and Remote Access


Motivated by a discovery by Radchenko and Viazovska and by a work by Ramos and Sousa, we find conditions sufficient for a pair of discrete subsets of the real axis to be a uniqueness or a non-uniqueness pair for the Fourier transform. These...


Analysis and Mathematical Physics

Lipschitz Graphs in Carnot Groups
2:30pm|Simonyi Hall 101 and Remote Access

Submanifolds with intrinsic Lipschitz regularity in Carnot groups (i.e.,
stratified groups endowed with a sub-Riemannian structure) can be
introduced using the theory of intrinsic Lipschitz graphs started years
ago by B. Franchi, R. Serapioni and F...
