We introduce and discuss some new stochastic models of optimal portfolio selection with reduced impact of forecast errors. In particular, we found some new examples of optimal myopic strategies, including some discrete time models with serial...

Speaker: Daniel Dugger (U.Oregon) Title: Motivic stable homotopy groups Speaker: Chad Giusti (U.Oregon) Title: Unstable Vassiliev theory Speaker: Veronique Godin (U.Calgary) Title: Relative invariant of string topology Speaker: Jose Maria Cantarero...

In this talk, designed for a broad mathematical audience, we will describe what is known (and unknown) about the classification of smooth 4-manifolds. In particular we will uncover a new mechanism that makes progress towards the conjecture that every...

In addition to frequent single-nucleotide mutations, mammalian and many other genomes undergo rare and dramatic changes called genome rearrangements. These include inversions, fissions, fusions, and translocations. Although analysis of genome...

The main topic of this talk is the non-linear stochastic wave equation in spatial dimension greater than 3 driven by spatially homogeneous Gaussian noise that is white in time. In dimensions greater than 3, the fundamental solution of the wave...

The basic reproductive number, R_0, which is generally defined as the expected number of secondary infections per primary case in a totally susceptible population, is an important epidemiological quantity. It helps us to understand the possible...

This is joint work with Eric Friedlander, Julia Pevtsova and Andrei Suslin. We consider modules over an elementary abelian group on which every element in the radical, but not the square of the radical, has the same Jordan canonical form. Such...

In this talk I show that the space of almost commuting elements in a compact Lie group G splits after one suspension.

The aim of this talk is to highlight the usefulness of continuous time branching process theory in understanding refined asymptotics about various random network models. We shall exhibit their usefulness in two different contexts: (1) First passage...
