The aim of this work is to study the unknown intervals of the lattice of aperiodic pseudovarieties which are semidirectly closed and answer questions proposed by Almeida in his book "Finite Semigroups and Universal Algebra". The main results state that the intervals [V \* (B2); ER โฉ LR] and [V \* (B
Ash's proof of the Pointlike Conjecture provides an algorithm for calculating the group-pointlike subsets of a finite semigroup S. We denote by P G S the subsemigroup of P S , the elements of which are the group-pointlike subsets of S. This paper is concerned with some properties of the operator G ,
