AbstractIf S is an irreducible semigroup of complex matrices and if every member of S has nonnegative diagonal entries, then is S simultaneously similar to a semigroup of nonnegative matrices? Partial affirmative answers to this and its infinite-dimensional analogue are given and several counterexamples presented
