Streszczenie
We establish an inversion formula of Post–Widder type for $\lambda ^{\alpha }$-multiplied vector-valued Laplace transforms ($\alpha >0$). This result implies an inversion theorem for resolvents of generators of $\alpha $-times integrated families (semigroups and cosine functions) which, in particular, provides a unified proof of previously known inversion formulae for $\alpha $-times integrated semigroups.
