Past Events

In this talk I will talk about some of my favorite problems which remain open in the field of continuous-time quantum walks in graphs.

I will report on joint work with Billerey, Dieulefait, Freitas, and Najman in which we develop some of the necessary ingredients to use Frey abelian varieties in the modular method, inspired by ideas from Darmon's program for resolving generalized...

Data science involves the collection, management, processing, analysis, visualisation and interpretation of huge amounts of data. It is a multi-disciplinary field that integrates systematic thinking, methodology, process and technology to develop...

A broadcast on a connected graph G with vertex set V(G) is a function f:V(G) ➛ {0, 1, ..., diam(G)} such that f(v) ≤ e(v), where e(v) denotes the eccentricity of v. If f(v) > 0, the vertex v is said to broadcast at strength f(v). In generalizing...

The method of cutting and stacking has long been used in ergodic theory. As a useful tool for constructing stationary and ergodic processes with desired properties, this method should also be powerful in solving information theoretic problems. In...

About 100 years ago, William Henry Young and Felix Hausdorff provedthat, for a periodic L_p-integrable function, the sequence of its Fourier coefficients necessarily lies in the discrete \ell_{p'} space provided that p' is the conjugate of p and 1

The blow up of the anticanonical base point on X, a del Pezzo surface of degree 1, gives rise to a rational elliptic surface E with only irreducible fibers. The sections of minimal height of E are in correspondence with the 240 exceptional curves on...
