Hermann Weyl Lectures

O-minimality and Ax-Schanuel properties
2:00pm|Simonyi Hall 101

This lecture will describe the historical context and some key properties of o-minimality. It will then describe certain results in functional transcendence, generalizing the classical results on exponentiation due to Ax, and sketch how they can be...

Variational Methods in Geometry Seminar

Existence of infinitely many minimal hypersurfaces in closed manifolds
Antoine Song
3:30pm|Simonyi Hall 101

In the early 80’s, Yau conjectured that in any closed 3-manifold there should be infinitely many minimal surfaces. I will review previous contributions to the question and present a proof of the conjecture, which builds on min-max methods developed...

Hermann Weyl Lectures

Point-counting and diophantine applications
2:00pm|Simonyi Hall 101

This introductory lecture will describe results about counting rational points on certain non-algebraic sets and sketch how they can be used to attack certain problems in diophantine geometry and functional transcendence.

Symplectic Dynamics Working Group

A rudimentary introduction to some questions on zero entropy conservative surface dynamics
1:30pm|Simonyi Hall Classroom 114

We shall discuss some basic results on surface diffeomorphisms. Then we introduce some results which were studied by both symplectic method and dynamical method. Finally we introduce some related questions.

Computer Science/Discrete Mathematics Seminar II

Small-Set Expansion on the Grassmann Graph.
Dor Minzer
10:30am|Simonyi Hall 101

A graph G is called a small set expander if any small set of vertices contains only a small fraction of the edges adjacent to it. This talk is mainly concerned with the investigation of small set expansion on the Grassmann Graphs, a study that was...

Symplectic Dynamics/Geometry Seminar

A local systolic inequality in contact and symplectic geometry
Gabriele Benedetti
3:30pm|Fine Hall 224

In this talk, which reports on joint work with Jungsoo Kang, we formulate a local systolic inequality for Reeb flows and Hamiltonian diffeomorphisms, which we establish in low dimension. As a consequence, we derive bounds for the minimal magnetic...

Members’ Seminar

New and old results in the classical theory of minimal and constant mean curvature surfaces in Euclidean 3-space R^3
William Meeks
2:00pm|Simonyi Hall 101

In this talk I will present a survey of some of the famous results and examples in the classical theory of minimal and constant mean curvature surfaces in R^3. The first examples of minimal surfaces were found by Euler (catenoid) around 1741...

Theoretical Machine Learning Seminar

Learning in Non-convex Games with an Optimization Oracle.
Alon Gonen
12:15pm|Princeton University, CS 302

We consider adversarial online learning in a non-convex setting under the assumption that the learner has an access to an offline optimization oracle. In the most general unstructured setting of prediction with expert advice, Hazan and Koren (2016)...

Computer Science/Discrete Mathematics Seminar I

Approximating the edit distance to within a constant factor in truly subquadratic time.
Mike Saks
11:15am|Simonyi Hall 101

Edit distance is a widely used measure of similarity of two strings based on the minimum number of character insertions, deletions, and substitutions required to transform one string into the other. The edit distance can be computed exactly using a...

Analysis Seminar

Some recent results related to the strong openness property of multiplier ideal sheaves.
Qi\'an Guan
4:30pm|Simonyi Hall 101

In this talk, we will recall the strong openness property of multiplier ideal sheaves (conjectured by Demailly and proved by Guan-Zhou), and then present some recent related progress including some joint work with Professor Xiangyu Zhou.
