Abstract: | A path integral expression for closed Nambu-Goto strings interacting by breaking and joining is shown to be pathological by using an equivalent euclidean lattice field theory. A class of interactions which correct this problem is discussed. Dyson-Schwinger equations are derived for string vacuum expectation values. |
