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.

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.
