On the product of semigroups of operators

Web24 de mar. de 2024 · Semigroup A mathematical object defined for a set and a binary operator in which the multiplication operation is associative . No other restrictions are placed on a semigroup; thus a semigroup need not have an identity element and its elements need not have inverses within the semigroup. A semigroup is an associative … Web2. Results for semigroups In this section we denote by T a strongly continuous semigroup of linear operators on the Banach space X. We remind the reader here that the semi-group T is called compact if T(t) is a compact linear operator on X for every i>0.
