L-R smash products for bimodule algebras
In this paper, we prove that the L-R smash product A (＃)H is exactly the twisted smash product A * H if H is a finite dimensional cocommutative Hopf algebra, and give a sufficient and necessary condition for L-R smash products to be bialgebras (Hopf algebras). For any finite dimensional coquasitriangular Hopf algebra (H, σ), we prove that the L-R smash product H (＃)H is semisimple Artinian if H is semisimple and H* is unimodular. In particular, the L-R smash product D(H) * (＃)D(H) * semisimple Artinian if the Drinfel' d double D(H) is semisimple.
