标题： D-instanton Induced Effective Action and its Gauge Invariance

摘要： D-instantons 对闭弦散射振幅的影响可以被编码到一个有效作用量中，该作用量通过积分掉(瞬态)开弦场得到。 为了使这尊重理论的规范不变性，微扰闭弦场论作用量和 D-instanton 诱导的有效作用量之和必须满足量子 Batalin-Vilkovisky 主方程。 在之前的一篇论文中，这是针对最多两个 instantons 诱导的有效作用量证明的。 我们将这个证明推广到任意数量的 D-instantons。 显示英文摘要

摘要： The effect of D-instantons on closed string scattering amplitudes may be encoded into an effective action obtained by integrating out the (transient) open string fields. In order that this respects the gauge invariance of the theory, the sum of the perturbative closed string field theory action and the D-instanton induced effective action must satisfy the quantum Batalin-Vilkovisky master equation. In a previous paper this was proved for the effective action induced by up to two instantons. We generalize the proof for arbitrary number of D-instantons.
