Algebra, Geometry and Combinatorics Day (AlGeCom) is a one day, informal meeting of mathematicians from the University of Illinois, Purdue University and nearby universities, with interests in algebra, geometry and combinatorics (widely interpreted).

Further details will be posted here as they become available. Or you may contact the University of Illinois organizers Hal Schenck and Alexander Yong, or the Purdue organizers Uli Walther and Saugata Basu .


Next event : Spring, 2010

Date: May 1, 2010

Location: Department of Mathematics, Purdue University.

The talks will held at  MATH 175.

Title:   The relations among invariants of ordered points on the projective line
Abstract:
We consider the coordinate rings of GIT quotients of n points on the
projective line modulo automorphisms of the line. We describe generators and
relations. Kempe found generators in 1894. We find the ideal of relations in
these generators (based on joint work with John Millson, Andrew Snowden, and
Ravi Vakil.)



Coffee and snacks          13h30

Peter Scheiblechner (Purdue)         16h - 17h

Food

There are many restaurants (including Indian, Chinese, Middle-eastern, Thai, Japanese, Greek, Mexican)  and several coffee-houses in and around campus as well as across the river in the town of Lafayette. See here for dining options.

Accommodation

We have reserved a block of rooms at the Union Club Hotel  which is conveniently located on campus and a two-minutes walk to the Mathematics department.
