Cancellable elements of the lattice of epigroup varieties
Published 27 Mar 2018 in math.GR | (1803.09925v1)
Abstract: We completely determine all commutative epigroup varieties that are cancellable elements of the lattice EPI of all epigroup varieties. In particular, we verify that a commutative epigroup variety is a cancellable element of the lattice EPI if and only if it is a modular element of this lattice.
