Monadic algebras are type one modal algebras, in which the single operator behaves like a closure operation in a topological space, (so these are closure algebras) and, in addition, elements are closed if and only if they are open.
A monadic algebra is a closure algebra, , which satisfies: for all , , where, as usual, is a shorthand for .
