In this volume, topics are drawn from field theory, especially gauge
field theory, as applied to particle, condensed matter and gravitational
physics, and concern a variety of interesting subjects. These include
geometricalDtopological effects in quantum theory, fractional charge,
time travel, relativistic quantized fields in and out of thermal
equilibrium and quantum modifications of symmetry in physical
systems.Many readers will find this a useful volume, especially
theoretical physicists and mathematicians. The material will be of
interest to both the expert who will find well-presented novel and
stimulating viewpoints of various subjects and the novice who will find
complete, detailed and precise descriptions of important topics of
current interest, in theoretical and mathematical physics.
