Hi all, I have a question for algebra , Let A and B algebras. Suppose that B acts on A, is there a algebra homomorphism B --> Aut(A) ??
has GAP any function Automorphism of commutative algebras?? gap> G:=Group((1,2,3,4));; gap> A:=GroupRing(GF(3),G);; gap> Automorphism(A); Variable: 'Automorphism' must have a value gap> AutomorphismAlgebra(A); Variable: 'AutomorphismAlgebra' must have a value gap> Automorphisms(A); Variable: 'Automorphisms' must have a value gap> Automorphism(A); Variable: 'Automorphism' must have a value gap> AutomorphismOfAlgebra(A); Variable: 'AutomorphismOfAlgebra' must have a value gap> AutomorphismRing(A); Variable: 'AutomorphismRing' must have a value gap> AutomorphismOfRing(A); Variable: 'AutomorphismOfRing' must have a value thanks.
