Moshe Kamensky: Picard–Vessiot Structures

On Monday afternoon we will have a speaker presenting an application of model theory to a classical problem of differential algebra, see details below.   Moshe Kamensky The Hebrew University Title: Picard–Vessiot Structures Abstract: A Picard–Vessiot (PV) extension associated to a linear differential equation is the analogue, in differential Galois theory, of the splitting field of a polynomial. continue reading…
