Weakly Distributive and Sectionally *Semilattice

This study concerns with the concepts of dense element, pseudocomplemented semilattice, *semilattice, sectionally *semilattice and also the concept of *semilattice to each section (0, a) in a semilattice. It imparts an account on the connections of sectionally *semilattice with pseudocomplemented semilattices. We establish that sectionally pseudocomplemented semilattice is a sectionally *semilattice, but not conversely.
