BSFT-like action from cohomomorphism

Abstract By performing a field redefinition via a cohomomorphism on the Maurer-Cartan action of the A∞ algebra, we construct an action that reproduces the characteristic structure of boundary string field theory (BSFT), which we refer to as the BSFT-like action. We show that the...
