For every Bernstein function f we show that - f(A) generates a semigroup which is of the same ‘kind’ as the one generated by - A. As a special case we obtain that fractional powers - Aα, where α∈ (0 , 1) , are generators.en1424-32022021226652690Springerhttps://creativecommons.org/licenses/by/4.0/Bi-continuous semigroupsC-semigroupsSequential equicontinuitySubordinationMathematikJournal Article10.15480/882.368610.1007/s00028-021-00700-710.15480/882.36861802.05059Other
