About the Infinitesimal generator of C_0 semigroup:
If the linear operator A is not bounded, we can not own the semigroup of linear operators . The operators exist if A is bounded. In this case, we have a uniformly continuous semigroup.

This is not a good opening sentence
[edit]"In mathematics, a C0-semigroup, also known as a strongly continuous one-parameter semigroup, is a generalization of the exponential function."
This statement, although perhaps technically justifiable, is one of the most unhelpful opening sentences in all of Wikipedia. Surely there are far, far, far better ways to introduce the subject.2600:1700:E1C0:F340:C094:C0EE:CF8E:1106 (talk) 20:06, 9 August 2018 (UTC)
Proposed merge of Quasicontraction semigroup into C0-semigroup#Contraction semigroups
[edit]Splitting off this two-liner into a separate article does not seem useful, considering that the C0-semigroup article otherwise gives an overview over the various properties they can have. 1234qwer1234qwer4 13:17, 14 November 2023 (UTC)
Merger complete. Klbrain (talk) 17:44, 2 July 2024 (UTC)
