We study rational actions of a linear algebraic group G on an algebra V, and the Ε½ . Ε½ induced actions on Rat V , the spectrum of rational ideals of V a subset of Ε½ . . Spec V which often includes all primitive ideals . This work extends results of Moeglin and Rentschler to prime characteristic, oft
A function or a power series f is called differentially algebraic if it satisfies a Ε½ X Ε½ n. . differential equation of the form P x, y, y , . . . , y s 0, where P is a nontrivial polynomial. This notion is usually defined only over fields of characteristic zero and is not so significant over fields
## dedicated to helmut wielandt on his 90th birthday We show that the length l V of the spectral sequence of a Lie algebra extension acting on a module V with a submodule W is not bounded by any function of the lengths l V/W and l W .
