Special Year Seminar

Combinatorial Inequalities and Combinatorial Interpretations: Part II
2:00pm|Wolfensohn Hall

In the second talk, I will concentrate on polynomial inequalities and whether the defect (the difference of two sides) has a combinatorial interpretation.  For example, does the inequality  $x^2+y^2 \geq 2xy$  have a combinatorial proof and what...

Higher Dimensional Fourier Quasicrystals from Lee-Yang Varieties
Pavel Kurasov
2:30pm|Simonyi Hall 101 and Remote Access

Fourier Quasicrystals (FQ) are defined as crystalline measures $$ \mu = \sum_{\lambda \in \Lambda} a_\lambda \delta_\lambda, \quad \hat{\mu} = \sum_{s \in S} b_s \delta_s, $$ so that not only $ \mu $ (and hence $ \hat{\mu} $) are tempered...

Joint IAS/PU Groups and Dynamics Seminar

Non-escape of Mass for Arithmetic Quantum Limits on Hyperbolic 4-Manifolds
Alexandre de Faveri
4:30pm|Simonyi 101

The Arithmetic Quantum Unique Ergodicity (AQUE) conjecture predicts that the $L^2$ mass of Hecke-Maass cusp forms on an arithmetic hyperbolic manifold becomes equidistributed as the Laplace eigenvalue grows. If the underlying manifold is non-compact...

Special Year Seminar I

Combinatorial Inequalities and Combinatorial Interpretations: Part III
2:00pm|Simonyi 101

In the third talk, I will concentrate on inequalities for linear extensionsof finite posets.  I will start with several inequalities which do have a combinatorial proof.  I will then turn to Stanley's inequality and outline the proof why its defect...
