"Motivated by results from the theory of group actions
and of the theory of group graded rings, Cohen and Fishman asked in 1986 whether the smash product of a semisimple
Hopf algebra and a semiprime algebra is semiprime again.
We will give a survey on past results of this problems
and on recent developments by Linchenko and Montgomery
which give an affirmative answer in case A satisfies
a polynomial identity."
