This talk identifies thirty of the great algorithms of numerical analysis, from Gaussian elimination to automatic differentiation, and asks in each case: Who were the main inventors? Were they mathematicians or engineers, academics or industrialists...

This talk presents joint work with Kee Lam of UBC and Nancy Cardim, Maria Herminia de Mello, and Mario Olivero da Silva in Rio de Janeiro, Brazil. Given the total space of any orthogonal sphere bundle over a sphere, we determine its stable span and...

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...
