We show by a counter-example that the two basic operator inequalities in the typical sufficient conditions for conservativity of minimal quantum dynamical semigroups are, in fact, both necessary.
Keywords: minimal quantum dynamical semigroup, conservativity, complex Hilbert space, algebra of bounded operators, contraction semigroup
Mots-clés : Markov chain.
