The omega transformation takes a Schur function indexed by a partition to the Schur function indexed by the partition's transpose. In this joint work with Jeff Remmel, we explore a refinement of the omega transformation defined on the quasisymmetric...

Efficient algorithms have recently been developed for calculating dealiased linear convolution sums without the expense of conventional zero-padding or phase-shift techniques. For one-dimensional in-place convolutions, the memory requirements are...

"Think analog, act digital" is a motto that is relevant to scientific computing and algorithm design in a variety of disciplines, including numerical analysis, image/signal processing, and computer graphics. Here, we will argue that cardinal splines...

We analyze a coin-tossing model used to justify the sale of constant proportion debt obligations (CPDOs) and prove that it was impossible for CPDOs to achieve the Cash-In Event. In the best-case scenario in which the coin is two-headed, we show that...

The Cascade Topology Seminar is supported in part by grants from the National Science Foundation, the Pacific Institute for the Mathematical Sciences, and is a Mathematical Sciences Research Institute MER Network Conference. The support of these...

Many statistics researchers in the Pacific North-West affiliated with PIMS universities work in the area of environmetrics: climate change and its impacts, agriculture, forestry, fisheries, etc. The aim of this workshop is to discuss the idea of...

The calculus of functors provides a framework for analyzing functors of spaces, and more generally, model categories, in terms of polynomial-like approximations to the functors. In this talk, I will give an introduction to the calculus of functors...
