In mathematics, a Stone algebra or Stone lattice is a pseudocomplemented distributive lattice L in which any of the following equivalent statements hold for all
They were introduced by , and named after Marshall Harvey Stone.
The set is called the skeleton of L. Then L is a Stone algebra if and only if its skeleton S(L) is a sublattice of L.
Boolean algebras are Stone algebras, and Stone algebras are Ockham algebras.
