Introduction to string field theory. A pedestrian approach to the covariant formulation
Geoffrey B. West · University of North Texas Digital Library (University of North Texas) · 1986
A relatively elementary account is given of what a string field represents and what is involved in the construction of its covariant action. Emphasis is on drawing a correspondence with similar problems in ordinary field theory and, particularly, using the language and mathematics used in ordinary field theory. Only the free string is discussed. 17 refs., 3 figs. (LEW)
