Actions of formal groups on special quotients of algebras

Marilena Crupi, Gaetana Restuccia


Let k be a field of characteristic p > 0 and let F be a one dimensional commutative formal group over k. The endomorphisms of a k-algebra A that defines an action of F on A when A is isomorphic to the quotient B/pB, with B torsion free Zalgebra, are studied.
