Visions in Arithmetic and Beyond: Celebrating Peter Sarnak's Work and Impact

Rigidity of Kleinian Groups and Zariski Density in Higher Rank
Hee Oh
11:30am|Princeton University McDonnell A02

Abstract: Discrete subgroups of PSL(2,C) are called Kleinian groups and they are fundamental groups of complete oriented hyperbolic 3-manifolds/orbifolds. Except for countably many conjugacy classes, all Kleinian groups have infinite co-volume in...

Sign Patterns of the Mobius Function
Tamar Ziegler
10:00am|Princeton University McDonnell A02

Abstract: The Mobius function is one of the most important arithmetic functions. There is a vague yet well known principle regarding its randomness properties called the “Mobius randomness law". It basically states that the Mobius function should be...

Global Well-Posedness of Stochastic Abelian-Higgs in Two Dimensions
Sky Cao
2:30pm|Simonyi Hall 101 and Remote Access

There has been much recent progress on the local solution theory for geometric singular SPDEs. However, the global theory is still largely open. In my talk, I will discuss the global well-posedness of the stochastic Abelian-Higgs model in two...

Toric and Semitoric Symplectic Geometry: Progress and Challenges
Álvaro Pelayo
9:15am|Remote Access

Toric integrable systems, also known as symplectic toric manifolds, arise as examples in different contexts within geometry and related areas. Semitoric integrable systems are a generalization of toric integrable systems in dimension four. In this...

Continuous Symmetry Breaking: A Rigorous Approach
Sara Daneri
2:30pm|Simonyi Hall 101 and Remote Access

At the base of spontaneous pattern formation is universally believed to be the competition between short range attractive and long range repulsive forces. Though such a phenomenon is observed in experiments and simulations, a rigorous understanding...

New Algebraic Invariants of Legendrian Links
Lenhard Ng
9:15am|Remote Access

For the past 25 years, Legendrian contact homology has played a key role in contact topology. I'll discuss a package of new invariants for Legendrian knots and links that builds on Legendrian contact homology and is derived from rational symplectic...

Resolution of the Kohayakawa--Kreuter Conjecture
Raphael Steiner
10:30am|Simonyi Hall 101 and Remote Access

A graph $G$ is said to be Ramsey for a tuple of graphs ($H_1,...,H_r$) if every $r$-coloring of the edges of $G$ contains a monochromatic copy of $H_i$ in color $i$, for some $i$. A fundamental question at the intersection of Ramsey theory and the...
