Alexandr Kostochka - Department of Mathematics, University of Illinois at Urbana-Champaign
Mar 5, 2018 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Rettaliata Engineering Center, Room 104
Dvořák and Postle introduced DP-coloring to answer a question of Borodin on list-coloring of planar graphs. Formally, a DP-\(k\)-coloring of a graph \(G\) is not exactly a coloring, but is an independent set in an auxiliary graph \(H(G,k)\). However, DP-coloring has many properties... read more
Chao Tang - Center for Quantitative Biology, Peking University
Mar 5, 2018 - 12:50pm to 1:50pm
Department of Applied Mathematics - Seminar - Rettaliata Engineering Center, Room 032
Precise and robust patterns emerge in biology, especially during development. Dissecting the genetic interactions that lead to these patterns has been the corner stone in developmental biology. This is usually done by observing changes in the pattern when perturbing the system, e.g., by deletions... read more
Shibi Feng - Department of Applied Mathematics, Illinois Institute of Technology
Mar 1, 2018 - 10:00am to 11:00am
Department of Applied Mathematics - Seminar - Perlstein Hall, Room 108
We introduce a dynamic model of the default waterfall of derivatives CCPs and propose a risk-sensitive method for sizing the initial margin (IM), and the default fund (DF) and its allocation among clearing members. Using a Markovian structure model of joint credit migrations, our... read more
