Graduate Colloquium

Title: p- numbers... WHY?

Vaishavi Sharma - Tulane Univeristy

Abstract Title:

p- numbers... WHY?


Vaishavi Sharma - Tulane University

Abstract:

In this talk, I will start from scratch and introduce the p- numbers and discuss the field Qp. I'll go over some examples and applications and then finally talk a little about the problems we're working on.

Title: On ideals defining products of affine schemes

Robert Walker - University of Michigan

Abstract Title:

On ideals defining products of affine schemes


Robert Walker - University of Michigan

Abstract:

This is joint work with Irena Swanson found on arXiv:1806.03545. Given a polynomial ring C over a field and proper ideals I and J whose generating sets involve disjoint variables, we determine how to embed the associated primes of each power of I+J into a collection of primes described in terms of the associated primes of select powers of I and of J. We discuss applications to constructing primary decompositions for powers of I+J, and to attacking the persistence problem for associated primes of powers of an ideal.

Abstract Title: Recent issues and discoveries on stochatically modeled reaction networks
Jinsu Kim - UC Irvine

Abstract: A reaction network is a graphical configuration that describes an interaction between species (molecules). If the abundances of the network system is small, then the randomness inherent in the molecular interactions is important to the system dynamics, and the abundances are modeled stochastically as a jump by jump fashion continuous-time Markov chain. One of challenging issues facing researchers who study biological systems is the often extraordinarily complicated structure of their interaction networks. Thus, how to characterize network structures that induce characteristic behaviors of the system dynamics is one of the major open questions in this literature. In this talk, I will provide recent issues and discoveries on stochastically modeled reaction networks. Specifically, we will focus on existence of stationary distributions and the convergence rate for the process to its stationary distribution.

Colloquium

Title: Queueing networks in heavy traffic: History and some recent results

Arka Ghosh - Iowa State

Abstract Title: Queueing networks in heavy traffic: History and some recent results
Arka Ghosh - Iowa State

Abstract:

Stochastic processing networks arise as models in manufacturing, telecommunications, transportation, computer systems, the customer service industry, and biochemical reaction networks. Common characteristics of these networks are that they have entities (jobs, packets, vehicles, customers, or molecules) that move along routes, wait in buffers, receive processing from various resources, and are subject to the effects of stochastic variability through such quantities as arrival times, processing times, and routing protocols. The mathematical theory of queueing aims to understand, analyze, and control congestion in stochastic processing networks. In this talk, we will review some of the major developments in the last century with more emphasis on some common approximations used in the last couple of decades. In particular, we will discuss broad results for control of large networks as well as more detailed results for control of specific smaller networks, under heavy traffic approximations.
