Igor Cialenco - Department of Applied Mathematics, Illinois Institute of Technology
Feb 8, 2018 - 10:00am to 11:00am
Department of Applied Mathematics - Seminar - Perlstein Hall, Room 108
Over the course of two or three seminars, we will discuss some recent developments in the area of statistical inference for parabolic stochastic partial  differential equations. We will start from some simple inverse type problems  from stochastic ordinary differential equations (SDEs)... read more

Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 106
A classical theorem of Johansson from 1996 asserts that \(\chi(G)=O(\Delta/\ln\Delta)\) for triangle-free graphs \(G\) of maximum degree \(\Delta\). Johansson's original proof of this result was quite intricate and involved iterated applications of the Lov\'asz Local Lemma. Recently, Molloy has... read more

Department of Applied Mathematics - Colloquia - Rettaliata Engineering Center, Room 104
In stratified survey sampling, one divides a population into homogeneous subgroups and then draws samples from each subgroup independently. Stratification often permits accurate computation of statistics from a sample much smaller than required otherwise. One can stratify Markov chain Monte Carlo (... read more
