MATS421 PDE reading seminar, 3 cr, spring 2014
28.2. No seminar!
The reading seminar introduces stochastic tools for studying potential theory for partial differential equations. We mainly follow the book
Peter Mörters, Yuval Peres
Cambridge University Press, 2010.
The seminar is intended to be accessible also for graduate students outside stochastics (for example from analysis), so in the first meetings we will review the basic theory of Brownian motion.
However, one should recall, for example from Evans' lecture note below, the concepts of probability space and measure, random variable, independence, expectation and distribution.
Seminar on Fridays at 10.15-12.00, MaD355. The seminar kick-off on Fr 24.1.
