Abstract: We completely determine all commutative semigroup varieties that are cancellable elements of the lattice SEM of all semigroup varieties. In particular, we verify that a commutative semigroup variety is a cancellable element of the lattice SEM if and only if it is a modular element of this lattice.
Keywords: semigroup, variety, cancellable element of a lattice, modular element of a lattice.
