Fall 2019: Physics 234A - String Theory I.
In Polchinski's string theory volume 2, when discussing the GSO projection for the heterotic string he says: In the IIA and IIB superstrings the GSO projection acted separately on the left- and right-moving sides. This will be also true in any supersymmetric heterotic theory.
The string theory is defined as the theory in which the particles are no longer be the objects to deal with in the subject instead the one-dimensional strings are.
Hawking, Ellis (7); S. Weinberg (8), etc. Some of the problems given in BBS as homework task are actually well known string theory facts which are described in papers or textbooks, especially in GSW. References to equations of some textbook are given here in format book (formula), e.g. BBS (12.140) gives metric for an extremal black D3-brane.
String Theory: The main issue nowadays for theoretical physicists is the creation of a unified framework that will combine all the wide accepted theories and will accurately explain how the.

String theory is one of the most exciting and challenging areas of modern theoretical physics. This book guides the reader from the basics of string theory to recent developments. It introduces the basics of perturbative string theory, world-sheet supersymmetry, space-time supersymmetry, conformal field theory and the heterotic string, before describing modern developments, including D-branes.
