摘要：
It is shown that Witten's theory of interacting open strings, which seems to depend on an arbitrary choice of a string midpoint, does in fact possess reparametrization invariance, which is hidden by a midpoint-dependent choice of phase in the transition from first-quantized theory to field theory. An equivalent version of this theory is constructed, which is manifestly reparametrization invariant, but is not manifestly local in spacetime. © 1990.
