我们研究开放弦场论中与边缘形变相关的基于单位的解。我们发现，基于身份的边际解可以表示为基于楔形的解的差值加上形变的Becchi-Rouet-Stora-Tyutin精确态的积分。使用这个表达式，可以解析地计算基于身份的解的规范不变量重叠。此外，我们还证明，通过规范变换，重叠可以转化为具有边界电流积分的圆盘关联函数。
We investigate identity-based solutions associated with marginal deformations in open string field theory. We find that the identity-based marginal solutions can be represented as a difference of wedge-based solutions plus an integration of a deformed Becchi-Rouet-Stora-Tyutin exact state. Using this expression, the gauge invariant overlap can be calculated analytically for the identity-based solutions. Moreover, we show that, by gauge transformation, the overlap is transformed into a disk correlation function with the integrations of currents at the boundary.
