2D phenomena in Probability
This topics course will focus on two-dimensional phenomena in Probability coming mostly from statistical physics, including tilings, vertex models, percolation, Schramm–Loewner evolution, etc.

Sections Taught This Semester:
Brownian motion and stochastic calculus (Karatzas and Shreve)
16:642:591 - Topics in Probability & Ergodic Theory I
This course will cover topics in stochastic analysis at the graduate level. The topics will include continuous semimartingale theory: Brownian motion, continuous-time martingales, stochastic integration, Girsanov's theorem, stochastic differential equations, and diffusions. Time permitting, we will cover Levy processes, the Levy-Khintchine formula, and the semimartingale topology in stochastic integration.
