Affine semigroups over an arbitrary field
Affine semigroups over an arbitrary field
Let ℒ V denote the algebra of all linear transformations on an n -dimensional vector space V over a field Φ. A subsemigroup S of the multiplicative semigroup of ℒ V will be said to be an affine semigroup over Φ if S is a linear variety, i.e., a translate …
