First of three lectures in a series. Introduction to toric ideals, part I A basic introduction to toric ideals, which are of fundamental importance in computational algebra and algebraic statistics. In this introduction to toric ideals, we will cover equivalent definitions, basic properties, and examples of toric ideals. This will be the first in a series of 3 lectures.

Solving Polynomial Systems in the Cloud with Polynomial Homotopy Continuation
Polynomial systems occur in many fields of science and engineering.
Polynomial homotopy continuation methods apply symbolicnumeric
algorithms to solve polynomial systems.
We describe the design and implementation of our web interface
and reflect on the application of polynomial homotopy continuation
methods to solve polynomial systems in the cloud.
Via the graph isomorphism problem we organize and classify
the polynomial systems we solved. The classification with
the canonical form of a graph identifies newly submitted
systems with systems that have already been solved.
This is joint work with Nathan Bliss, Jeff Sommars, and Xiangcheng Yu.

Introduction to toric ideals, part II
An introduction to Markov bases: definitions, properties and examples. I will also make connections to my previous talk on toric ideals.

Tue, Sep 29 3:304:30pm 
E1102  Dane Wilburne, IIT
Markov Bases for Multinomial Logistic Regression Models: A Preliminary Report Wilburne will discuss Markov bases for multinomial logistic regression models and present partial progress toward obtaining sharp upper bounds for the elements in the basis. Wilburne will also explore the connection between these models and primitive partition identities (ppi).

Biased Infinity Laplacian Boundary Problem on finite graphs We provide an algorithm, running in polynomial time in the number of vertices, computing the unique solution to the Biased Infinity Laplacian Boundary Problem on finite graphs. The algorithm is based on an adjusted (biased) notion of a slope of a function on a path in a graph. The infinity Laplacian Boundary Problem has a probabilistic interpretation related to the expected outcome in a randomturn game on a graph under optimal play by both players. This is a joint work with Yuval Peres.
