Finite topological space — In mathematics, a finite topological space is a topological space for which the underlying point set is finite. That is, it is a topological space for which there are only finitely many points.While topology is mostly interesting only for… … Wikipedia
Meet (mathematics) — In mathematics, a meet on a set is defined either as the unique infimum (greatest lower bound) with respect to a partial order on the set, provided an infimum exists, or (abstractly) as a commutative and associative binary operation satisfying an … Wikipedia
Finite projective geometry — In mathematics, a finite projective space S is a set P (the set of points), together with a set of subsets of P (the set of lines), all of which have at least three elements, satisfying these axioms : * Each two distinct points p and q are in… … Wikipedia
Join and meet — In mathematics, join and meet are dual binary operations on the elements of a partially ordered set. A join on a set is defined as the (necessarily unique) supremum (least upper bound) with respect to a partial order on the set, provided a… … Wikipedia

Semilattice — In mathematics, a join semilattice (or upper semilattice) is a partially ordered set which has a join (a least upper bound) for any nonempty finite subset. Dually, a meet semilattice (or lower semilattice) is a partially ordered set which has a… … Wikipedia
