(i)We exploit the boundary state formalism to investigate duality between open-and closed-strings in superstring theory. By using the off-shell interactions of open-and closed-strings developed in our for- malism, we show that in the background of non-vanishing NS-NS two-form field, the masssive modes of closed-string emerge as the Wilson lines in non-commutative gauge theories on D-branes. (ii)In superstring compactifications, local Calabi-Yau geometries are related with thermodynamic quantities of certain statistical models. We study random plane partitions relevant to describe Nekrasov's par- tition functions of five-dimensional supersymmetric gauge theories, from both the gauge theory and gravity viewpoints. After taking a natural scaling, the thermodynamic limit corresponds to a classical limit with respect to g_<st>. We show that classical objects called the limit shapes of plane partition govern the systems. In particular, the limit shapes at zero temperature are equivalent to the local geometries while at finite temperature, they describe a quantum deformation of the local geometries.

(i)We利用边界态理论研究超弦理论中开弦和闭弦之间的对偶性。利用在我们的理论中发展的开弦和闭弦的离壳相互作用，我们证明了在非零NS-NS双形式场的背景下，闭弦的质量模以D-膜上非对易规范理论中的Wilson线的形式出现.（ii）在超弦紧化中，局部卡-丘几何与某些统计模型的热力学量有关。本文从规范理论和引力理论两个方面研究了与描述五维超对称规范理论Nekrasov粒子函数有关的随机平面配分。在采取自然标度之后，热力学极限对应于关于g的经典极限<st>。我们表明，经典的对象称为平面分区的极限形状管理系统。特别地，在零温度下的极限形状等价于局部几何，而在有限温度下，它们描述了局部几何的量子变形。
