Differential Algebra seminar

Organised by Anand Pillay and Frank Nijhoff.
Telephone: 0113 343 5171

In Autumn 2011 we will have, among other things, a series of talks around non linear differential Galois theory, trying to understand the Malgrange theory of Galois groupoids attached to a foliation, as well as discussing the model theoretic/differential algebraic approach via logarithmic differential equations on algebraic D-groups.
