Open and Closed StringsIn addition to the theory of closed strings just described, we may construct another consistent theory by considering world-sheets . with boundaries. Such a theory necessarily contains open strings. In this case, we can insert open string states to the boundaries and closed string states to the bulk of . as in Fig. 4.1.

String Theoryaningful and, in fact, at quantum level the former implies the latter. The action for the open string turns out to be structurally very similar to that of the point particle described in the previous chapter.
