Query: The endomorphism semiring of a commutative inverse semigroup   The authors [3] proved that the endomorphism semiring of a nontrivial
semilattice is always subdirectly irreducible and described its monolith. Here
we prove that the endomorphism semiring of a commutative inverse semigroup with
at least two idempotents is always subdirectly irreducible and describe its
monolith.
