Tannakian categories, linear differential algebraic groups, and parameterized linear differential equations

Alexey Ovchinnikov

Published 2007-03-14, updated 2008-09-16Version 3

We provide conditions for a category with a fiber functor to be equivalent to the category of representations of a linear differential algebraic group. This generalizes the notion of a neutral Tannakian category used to characterize the category of representations of a linear algebraic group.
