A functional calculus and fractional powers for multivalued linear operators. (English) Zbl 0979.47013
This is a continuation of the earlier work of the two first authors [Potential Analysis Theory 9, No. 4, 301-319 (1998; Zbl 0927.47011)]. The authors improve a functional calculus valid for a wider class of functions. By applying the functional calculus a theory of fractional powers for multivalued nonnegative linear operators is obtained.
