The Signature and Natural Slope of Hyperbolic Knots

Andras Juhasz has explained in his talk how machine learning was used to discover a previously unknown relationship between invariants in knot theory. This...

Growth of Bianchi modular forms
Weibo Fu
11:00am|Simonyi 101 and Remote Access

In this talk, I will establish a sharp bound on the growth of cuspidal Bianchi modular forms. By the Eichler-Shimura isomorphism, we actually give a sharp bound of the second cohomology of a hyperbolic three manifold (Bianchi manifold) with local...

What is Machine Learning Good For?

Machine learning has seen remarkable success in many areas in the past decade, but this inevitably leads to hype that obscures what it can and cannot do. In this talk we will...

Computer Science/Discrete Mathematics Seminar II

The absorption method, and an application to an old Ramsey problem
10:30am|Simonyi Hall 101 and Remote Access

The absorption method is a very simple yet surprisingly powerful idea coming from extremal combinatorics which allows one to convert asymptotic results into exact ones. It has produced a remarkable number of success stories in recent years with...

4:00pm|Simonyi 101 and Remote Access

Geordie Williamson, University of Sydney

Combinatorial Invariance: a Case Study of Pure Math / Machine  Learning Interaction

The combinatorial invariance conjecture is a fascinating conjecture in Representation Theory. Basically it says that...

Andras Juhasz
2:00pm|Simonyi 101 and Remote Access

Knot Theory and Machine Learning

Andras Juhasz, University of Oxford

The signature of a knot K in the 3-sphere is a classical  invariant that gives a lower bound on the genera of compact oriented surfaces in the 4-ball with boundary K. We say...

Linear cover time is exponentially unlikely
Quentin Dubroff
11:15am|Simonyi 101 and Remote Access

Proving a 2009 conjecture of Itai Benjamini, we show:  For any C, there is a > 0 such that for any simple random walk on an n-vertex graph G, the probability that the first Cn steps of the walk hit every vertex of G is at most exp[-an].  A first...

Three 20-min research talks
Benoît Joly, Marco Castronovo and Agniva Roy
9:15am|Remote Access

Benoît Joly (Ruhr-Universität Bochum), Barcodes for Hamiltonian homeomorphisms of surfaces

In this talk, we will study the Floer Homology barcodes from a dynamical point of view. Our motivation comes from recent results in symplectic topology using...
