Title: Free Bertini's theoremAbstract:Bertini's irreducibility theorem is a classical result ubiquitous in algebraic geometry. In its simplest form it states that the generic fiber of a non-composite polynomial function is an irreducible hypersurface. The talk presents its analog for a free associative algebra, some background and applications to matricial evaluations of noncommutative polynomials.

Title: MODEL REDUCTION TECHNIQUES AND NUMERICAL ANALYSIS IN A NUT SHELLAbstract:In this talk, we introduce some fundamental problems considered in the field of numerical analysis (AMS Class: 65). To approximate a solution of a partial differential equations, one may use some numerical methods to translate a continuous, abstract problem into a discrete, concrete linear system. Next, we discuss some useful model reduction techniques (for partial differential equa- tions) that make fast computation feasible in practical applications. Several numerical examples will be presented to illustrate these ideas.

Title: An invitation to Arakelov geometry.Abstract:The essence of Arakelov geometry lies in compactifying an 'arithmetic variety' defined over the spectrum of a number ring, and using the information from the resultant complex space. In this talk, I will motivate this picture when the arithmetic variety is the spectrum of the number ring itself.
