Ziteng Cheng - Department of Applied Mathematics, Illinois Institute of Technology
Mar 22, 2018 - 10:00am to 11:00am
Department of Applied Mathematics - Seminar - Perlstein Hall, Room 108
The filtering theory regards estimating an unobservable process X with the information of another (correlated) process Y. This talk aims to give an elementary introduction to the filtering theory under discrete Markov chain set up. Intuitions and mechanism behind the theory will be covered in... read more
Shu Wang - College of Applied Sciences, Beijing University of Technology
Mar 21, 2018 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Rettaliata Engineering Center, Room 104
I will discuss the asymptotic limit problems on some models arising from applied sciences such as semiconductor and plasma. The models include drift diffusion models and PNP models, etc, which usually concern small parameter regimes. Some new results on rigorous limits like quasi neutral limits are... read more
Mimi Dai - Department of Mathematics, Statistics, and Computer Science, University of Illinois at Chicago
Mar 8, 2018 - 12:50pm to 1:50pm
undefined - Seminar - Rettaliata Engineering Center, Room 119
In this talk we will review classical results on determining modes for fluid equations and present a slightly different approach where we start with a time-dependent determining wavenumber defined for each individual trajectory and then study its dependence on the force. While in some cases... read more
