Description
String Field Theory (SFT) aims to provide a non-perturbative formulation of string theory, and various types of actions have been constructed within this framework. Understanding the transformations between these actions leads to the unification of different formulations, the clarification of correspondences, and the proof of their equivalence. In recent years, T.Erler and H.Matsunaga have clarified the transformation between Witten-type SFT and light-cone SFT; however, the relationship with OSp-invariant SFT remains unclear. In this talk, I will discuss the BRST charge similarity transformations related to OSp-invariant SFT. This research is based on collaborative work with Y. Ando (Tohoku University).
