A construction of the Wehrl entropy is proposed for an arbitrary locally compact abelian group $G$. It is proved that the Wehrl entropy is not less than a certain nonnegative integer, which is an invariant of the group $G$. The minimum of the Wehrl entropy is attained on coherent states.
Keywords: coherent states, Wehrl entropy
Mots-clés : commutation relations.
