Boris Munevich Vernikov · Mathematical Notes · 2010
A description of distributive, codistributive, standard, costandard, and neutral elements of the lattice of overcommutative varieties of semigroups was proposed in the paper.In order to state this result more precisely, we need some notation.Suppose that m and n are natural numbers, 2 ≤ m ≤ n.By the partition of the number n into m parts we mean a sequence λ = (ℓ 1 , ℓ 2 , . . ., ℓ m ) of natural numbers such that
