Description
Book SynopsisGauge theories have provided our most successful representations of the fundamental forces of nature. How, though, do such representations work? Interpretations of gauge theory aim to answer this question. Through understanding how a gauge theory''s representations work, we are able to say what kind of world our gauge theories reveal to us.A gauge theory''s representations are mathematical structures. These may be transformed among themselves while certain features remain the same. Do the representations related by such a gauge transformation merely offer alternative ways of representing the very same situation? If so, then gauge symmetry is a purely formal property since it reflects no corresponding symmetry in nature.Gauging What''s Real describes the representations provided by gauge theories in both classical and quantum physics. Richard Healey defends the thesis that gauge transformations are purely formal symmetries of almost all the classes of representations provided by each of
Trade ReviewI loved this book. It is not an easy read, but it is deeply rewarding - an important monograph and a useful reference all in one. Its 2008 Lakatos prize was well-earned. * David John Baker Mind 119 *
Healey's book is a major achievement that will undoubtably serve as a valuable reference work as well as stimulate further debate and research. * Ward Struyve, Notre Dame Philosophical Reviews *
