A note on a formula for the fractional powers of infinitesimal generators of semigroups
Celso Martinez, Miguel Sanz (1996)
Studia Mathematica
If -A is the generator of an equibounded -semigroup and 0 < Re α < m (m integer), its fractional power can be described in terms of the semigroup, through a formula that is only valid if a certain function is nonzero. This paper is devoted to the study of the zeros of .

A note on Howe's oscillator semigroup

Annales de l'institut Fourier
Analytic extensions of the metaplectic representation by integral operators of Gaussian type have been calculated in the and the Bargmann-Fock realisations by Howe [How2] and Brunet-Kramer [Brunet-Kramer, Reports on Math. Phys., 17 (1980), 205-215]], respectively. In this paper we show that the resulting semigroups of operators are isomorphic and calculate the intertwining operator.
A note on maximal estimates for stochastic convolutions

Czechoslovak Mathematical Journal
In stochastic partial differential equations it is important to have pathwise regularity properties of stochastic convolutions. In this note we present a new sufficient condition for the pathwise continuity of stochastic convolutions in Banach spaces.

A notion of analytic generator for groups of unbounded operators
José E. Galé (2005)
Banach Center Publications
We introduce a notion of analytic generator for groups of unbounded operators, on Banach modules, arising from Esterle’s quasimultiplier theory. Characterizations of analytic generators are given in terms of the existence of certain functional calculi. This extends recent results about C₀ groups of bounded operators. The theory is applicable to sectorial operators, representations of , and integrated groups.
