Tannakian categories, linear differential algebraic groups, and parameterized linear differential equations
Alexey Ovchinnikov
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…

Tannakian approach to linear differential algebraic groups
Alexey Ovchinnikov
Tannaka's Theorem states that a linear algebraic group G is determined by the category of finite dimensional G-modules and the forgetful functor. We extend this result to linear di…
