We give a model for the moduli space of Riemann surfaces with one or more boundary curves using harmonic functions and canonical tesselations. The resulting simplicial complex is homeomorphic to a flat vector bundle over the moduli space.

The simplest models of population genetics, useful as they are in analyzing data, often have obvious shortcomings. Such models might ignore the effects of natural selection, mutation, or, as we will be concerned with in this talk, geography and...

This talk presents some coherent though incomplete conjectures for the emergence, replication and abundance of some chemical structures found in each prokaryote, with special emphasis on the trines and the rRNA filaments that constitute a large part...

Linear operators are at the core of many of the most basic algorithms for signal and image processing. Matlab's high-level, matrix-based language allows us to express naturally many of the underlying matrixoperations---e.g. computation of matrix...

Math Mania presents a variety of interactive demonstrations, games and art such as soap bubbles, 'get your goat' (Monty Hall game), the penny game, the Set Game, the 'Game of 24', kaleidoscopes and hexaflexagons, Nim, Tower of Hanoi, the amazing...

A basic question in probabilistic potential theory is the following: Consider a random proper subset K of R^d, for what nonrandom sets A is P{K intersect A not equal 0}? In this lecture we will give some abstract results when K is the range of a...

I will first describe a result on the uniqueness of invariant distributions for a certain process of coagulation and fragmentation. This result was firstproved by Diaconis, Mayer-Wolf, Zeitouni and Zerner (2004) using representation theory, but...
