"The
Algebra of Essential Relations on a Finite Set"
By
Abstract: In
this joint work with Jacques Thévenaz, we study the
structure of the algebra E(X) of essential relations on a finite set X: this algebra (which doesn't seem to
have been considered so far) is the quotient of the algebra of the monoid of all
relations on X by the submodule generated by
relations which factor through a
(strictly) smaller set. In particular, we determine all the simple E(X)-modules.
