The Rees factor semigroup is a mathematical structure studied in the field of algebra, specifically in semigroup theory. It is named after the mathematician R. J. Rees, who contributed to the development of semigroup theory. A Rees factor semigroup is constructed from a semigroup \\( S \\) and a congruence relation \\( \\theta \\) on \\( S \\).
