Definable groups of automorphisms
Abstract: The Galois theory of linear differential equations can be usefully
interpreted as an instance of the general model theoretic construction
of the automorphisms group of one definable set over another. I will
present an elementary version of this construction, which is useful for
interpreting the Galois group of a linear difference equation.
