The subject of the book includes the study of control problems for
systems which are encountered in viscoelasticity, non-Fickian diffusion
and thermodynamic with memory. The common feature of these systems is
that memory of the whole past history persists in the future. This class
of systems is actively studied now, as documented in the recent book.
This book will attract a diversified audience, in particular, engineers
working on distributed systems, and applied mathematicians. Background
of mathematics are the elements of functional analysis, which is now
standard among people working on distributed systems, and the author
describes very clearly the instruments which are used at every step.
