|This title gives an up-to-date account of the theory of one-parameter semi groups of linear evolution equations.|
|The subject of this book is one-parameter semigroups in L(X). A non-empty |
subset A⊆L(X) is called a semigroup if T,S∈A⇒T◦S∈A (∀T,S∈A).
AsemigroupA is called abelian if T◦S=S◦T (∀T,S∈A). The definitions of an
idempotent, unit, ...
|Let 5 be a topological semigroup. A one-parameter semigroup of 5 is a |
continuous homomorphism a: R+ — > S. We often require also that cr(0) — 1 ,
where 1 is an identity of 5. One-parameter semigroups, as distinct from one-
|PART TWO BASIC PROPERTIES OF SEMI-GROUPS Summary. Except for two |
chapters, the remainder of this treatise is devoted to the theory of semi-groups
with special reference to one-parameter semi-groups of endomorphisms of a ...

|The holomorphic self-maps which belong to one-parameter semigroups enjoy |
the property of being injective, which gives a first, very primitive condition on a
self-map of X in order to be a contained in a one-parameter semigroup.
