Abstract

We investigate the possibility that stringy nonperturbative effects appear as holes in the world sheet. We focus on the case of Dirichlet string theory, which we argue should be formulated rather differently than in previous work, and we find that the effects of boundaries are naturally weighted by e^\mathrm\ensuremath-O(1/g_st).
