Distributive Lattice:

A type of lattice where the join and meet operations distribute over each other, meaning that for any elements a, b, and c, the equations a ∨ (b ∧ c) = (a ∨ b) ∧ (a ∨ c) and a ∧ (b ∨ c) = (a ∧ b) ∨ (a ∧ c) hold.

Stone Representation Theorem:

A fundamental result in topology and order theory that establishes a correspondence between certain algebraic structures and topological spaces, providing insight into their dual nature.

Topological Space: A set equipped with a topology, which is a collection of open sets satisfying certain axioms, enabling the study of convergence, continuity, and compactness in mathematics.
