We show that these extensions are in one-to-one correspondence with finite dimensional associative commutative algebras. We also construct a special kind of these extensions, that correspond to a finite commutative monoids.LaTex, no figuresRings and AlgebrasDynamical Systems37K30 (Primary) 37K05, 17B80 (Secondary)text
