Query: Tannakian formalism over fields with operators   We develop a theory of tensor categories over a field endowed with abstract
operators. Our notion of a "field with operators", coming from work of Moosa
and Scanlon, includes the familiar cases of differential and difference fields,
Hasse-Schmidt derivations, and their combinations. We develop a corresponding
Tannakian formalism, describing the category of representations of linear
groups defined over such fields. The paper extends the previously know
(classical) algebraic and differential algebraic Tannakian formalisms.
