The functional calculus for sectorial operators

More about the book

First systematic account of functional calculus for sectorial (and other types of unbounded) operators Emphasizes the calculus aspect of the matter, thus paving the way for making functional calculus a working tool A chapter on fractional powers combines elegance with comprehensibility, even in the most general setting The Hilbert space results, duly arranged and comprehensibly presented, appear in book form for the first time Includes supplementary material: sn. pub/extras
