Introduction to String Theory

Warren Siegel9789971507312, 9971507315

“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. ” B R Parker Choice, USA, 1989 “Siegel has played a major role in the application of BRST formalisms for quantization to string theory … Siegel’s book is of great interest for those who intend to do research in string field theory.” O W Greenberg Foundations of Physics, USA, 1991
