Please bring your favourite (math) problems. Anyone with a problem to share will be given about 5 minutes to present it. We will also choose most of the speakers for the rest of the semester.

We discuss the possibility that the Riemann zeta function has a zero s+iT to the left of the classical zero free region. We will show how the existence of this zero forces the function to have many more zeros in the vicinity of s+iT or/and s+2iT.

Place a checker in some square of an m x n rectangular checkerboard, and glue opposite edges of the checkerboard to make a projective plane. We determine whether the checker can visit all the squares of the checkerboard (without repeating any squares...

In this talk, I will discuss a characterization of linear isometries between certain subspaces of Banach-space valued spaces of continuous functions. The result is motivated by some prior results on isometries between some spaces of vector-valued di...

In this talk we will outline a large class of problems in Analysis (in particular, Matrix Analysis) called the Preserver Problems and then concentrate on a specific preserver problem: study the structure of isometries defined on the algebra A of...

A Cayley object over a finite group H is any relational structure R with point set H which is invariant under the group of right translations. The well-known examples of Cayley objects include Cayley graphs, Cayley maps, group codes etc. The...

An association scheme is a coloring of a complete graph satisfying certain regularity conditions. It is a generalization of groups and has many applications in algebraic combinatorics. Every association scheme yields a special matrix algebra called...

Hardy and Littlewood initiated the study of the 2k-th moments of the Riemann zeta function on the critical line. In 1918 Hardy and Littlewood established an asymptotic formula for the second moment and in 1926 Ingham established an asymptotic formula...

We describe a theorem of M. Mourtada and V. Kumar Murty on the distribution of values of the logarithmic derivative of the L-functions attached to quadratic characters. Under the assumption of the generalized Riemann Hypothesis they prove the...

In this talk, I will briefly review the basic modeling of Mathematical Finance, and then focus on how to numerically measure the risk of a financial position. For the latter purpose, we will introduce the notions of coherent risk measures and convex...
