Topological spaces as algebras
 
 
Description: 

Monads, or triples, and the algebras they define, proved to be very important in several fields of mathematics. For example, they allow us to see the algebraic nature owned by topological spaces. This fact, for what concerns compact Hausdorff spaces, is known since 1969 (see [4]). By suitably weakening the axioms of the algebras, M. Barr in 1970 (see [1]) generalized the result to all topological spaces. This step represented a starting point of the new theory of lax (Eilenberg-Moore) algebras, introduced about thirty years later by M.M. Clementino, D. Hofmann and W. Tholen (see [2] and [3]).
