Abstract:
These notes are intended to serve as the first chapter of a forthcoming book on "Semigroups of operators and their applications", the applications being in the areas of differential equations, Markov processes, and mathematical physics. At the end of these notes, is given a Bibliography which lists certain books and monographs in functional analysis that the reader may wish to consult for proofs of theorems given in the notes, and for additional results and comments.
