Examples of B-Module Algebras
ABSTRACT: Let
A is an associative algebra and B a bialgebra. A B-module algebra
structure on A is an action of B on A such that the comultiplication on
bialgebra B is compatible with the multiplication on algebra A. In this
case, for example, group-like elements of the bialgebra act on A as
algebra homomorphisms, and primitive elements of B act on A as
derivations. In this lecture, we consider bialgebras that give rise to
B-module algebra structures on polynomial, Weyl, and quiver algebras.
