H ∞ Functional Calculus and Characterization of Domains of Fractional Powers
Atsushi Yagi · Birkhäuser Basel eBooks · 2008
Characterization of the domains of fractional powers of linear operators is very important in the study of (linear or nonlinear) abstract parabolic evolution equations. In this paper we present a new method of utilizing the H ∞ functional calculus of linear operators.
