MeetSemilattice overview

A meet-semilattice (or lower semilattice) is a semilattice whose operation is called meet, and which can be thought of as a greatest lower bound.

A MeetSemilattice must satisfy the following laws:

  • Associativity: a ∧ (b ∧ c) <-> (a ∧ b) ∧ c
  • Commutativity: a ∧ b <-> b ∧ a
  • Idempotency: a ∧ a <-> a
