摘要：

The sum over topologies of dilaton tadpole divergences in the bosonic string obeys a differential equation. By solving the equation we sum the leading divergences and obtain a non-perturbative contribution to the effective action. We discuss the physical interpretation and relevance of the non-perturbative terms. © 1990.
