Channel Assignments in Infinite Graph

We study quaternionic (especially hyperkahler) analogues of Lerman's symplectic cut construction. In low dimensions this can be physically interpreted as adding a brane to a hyperkahler manifold   more››

Climate Risk, Securitization, and Equilibrium Bond Pricing

We propose a method of pricing financial securities written on non-tradable underlyings such as temperature or precipitation levels. To this end, we analyze a financial market where agents are exposed to financial and non-financial risk factors. The   more››

Some applications of the graph of supersingular elliptic curves over a finite field

The graph of supersingular elliptic curves over a finite field connected by isogenies has many applications in computational number theory. In this talk we look at some old (in number theory) and new (in cryptography) applications of these gr   more››

Pathwise uniqueness for parabolic stochastic pde's

Consider the SPDE: du/dt=u''+g(u)dW/dtdx where dW/dtdx is space-time white noise and g is Holder continuous of index h. It is shown that if 2h^3-h > 3/4 then pathwise uniqueness holds. The proof is an infinite dimensional extension of the Yamada-W   more››

Commuting Elements in Lie Groups

In this talk we discuss the topology and geometry of the space of pairs of commuting elements in a Lie group. We will see part of the work of Adem and Cohen on SU(2) as well as some recent advances in the case of U(2).   more››

Activation Analysis in Functional Magnetic Resonance Brain Imaging with Applications in Parkinsons Disease

This talk will present some of our recent work on spatial characterization of activation patterns in functional magnetic resonance imaging (fMRI) of the brain. Exploiting techniques for region of interest (ROI) characterization and statistical a   more››
