INTRODUCTION TO STRING FIELD THEORY

&ldquo,For anyone interested in the rapidly developing field of string theory (graduate students with the proper physics background), Siegel',s book is a particularly good introduction.&rdquo,>,/p>,Choice, USA &ldquo,Siegel has played a major role in the application of BRST formalisms for quantization to string theory &hellip, Siegel',s book is of great interest for those who intend to do research in string field theory.&rdquo,Foundations of Physics, USA ,This volume covers the most up-to-date findings on string field theory. It is presented in a new approach as a result of insights gained from the theory. This includes the use of a universal method for treating free field theories, which allows the derivation of a single, simple, free, local, Poincare-invariant, gauge-invariant action that can be applied directly to any fields._,
