Extremal length is a conformal invariant that plays an important role in Teichmueller theory. For each essential closed curve on a Riemann surface, it furnishes a function on the Teichmueller space. The extremal length systole of a Riemann surface is...

Epithelial-mesenchymal transition (EMT), a process in which immotile cells that line surfaces in the body become motile mesenchymal cells, play a crucial role in major processes such as wound healing, embryo development, and cancer growth; therefore...

For every non-elementary hyperbolic group, we consider the Manhattan curve, which was originally introduced by M. Burger (1993), associated to any pair of (say) word metrics. It is convex; we show that it is continuously differentiable and moreover...

Abstract For cells to divide, they must undergo mitosis: the process of spatially organizing their copied DNA (chromosomes) to precise locations in the cell. This procedure is carried out by stochastic components that manage to accomplish the task...

Abstract I will present a history and overview of some of the work that has been done on the lexicographic product of graphs, and related generalisations. The focus of my talk will be on the automorphism groups of such graphs, and the relationship to...

Abstract: The decade of the 2010s was the hottest yet in more than 150 years of global mean temperature measurements. The key climate change signatures include intensifying extreme events such as widespread droughts, flooding and heatwaves, severe...

I'll discuss recent joint work with Alex Wright ( arXiv:2103.07496) showing that typical large genus hyperbolic surfaces have first Laplacian eigenvalue at least 3/16−ϵ.

May 12 - 15, 2021: Movie Screening* Picture a Scientist is a feature-length documentary film chronicling the groundswell of researchers who are writing a new chapter for women scientists. A biologist, a chemist and a geologist lead viewers on a...

The West Coast Optimization Meeting will take place on May 13, 2021. The organizers are pleased to invite you to a virtual West Coast Optimization Meeting (WCOM). All talks take place through zoom. Please check back this page frequently and watch for...

PIMS workshop on New Trends in Localized Patterns in PDEs: Mathematical Theory and Applications to Physics, Biology and the Social Sciences- a Conference in Honour of the 60th Birthday of Michael J. Ward. Localized spatial-temporal patterns commonly...
