The Kolchin Seminar

Saturday, October 19th, 2002

Hunter West, Room HW706

Professor David Marker

University of Illinois, Chicago

Model Theory and Differential Algebraic Geometry I

2:00 – 3:00 PM

Abstract: The model theoretic analysis of differentially closed fields leads to a number of fascinating problems about the geometry of Kolchin closed sets. I will survey some of the model theoretic background, recent results and open problems in this area.

Professor V. S. Varadarajan

UCLA and CIMS

Commutative Algebra, Group Theory, and Meromorphic Differential Equations

3:30 – 4:45 PM

Abstract: In this talk I shall look at the problems of local reduction of meromorphic differential equations, individual as well as depending on parameters, from the perspective of commutative algebra and group theory. Some of the issues discussed will be derivation of normal forms including the parametric setting, construction of moduli spaces, and so on. The emphasis will be on irregular singular equations.
