This is the first comprehensive reference published on heat equations
associated with non self-adjoint uniformly elliptic operators. The
author provides introductory materials for those unfamiliar with the
underlying mathematics and background needed to understand the
properties of heat equations. He then treats *Lp
- properties of solutions to a wide class of heat equations that have
been developed over the last fifteen years. These primarily concern the
interplay of heat equations in functional analysis, spectral theory and
mathematical physics.
This book addresses new developments and applications of Gaussian upper
bounds to spectral theory. In particular, it shows how such bounds can
be used in order to prove *Lp
- estimates for heat, Schrödinger, and wave type equations. A
significant part of the results have been proved during the last decade.
The book will appeal to researchers in applied mathematics and
functional analysis, and to graduate students who require an
introductory text to sesquilinear form techniques, semigroups generated
by second order elliptic operators in divergence form, heat kernel
bounds, and their applications. It will also be of value to mathematical
physicists. The author supplies readers with several references for the
few standard results that are stated without proofs.
