Open-Closed-Open Triality for 1/2 BPS Three-Point Functions
Keisuke Konosu, Kenta Suzuki
Open-closed-open triality relates two distinct open string descriptions through a common closed string theory. In this paper, we develop an open-closed-open triality for protected…
The LSZ reduction formula from homotopy algebras
Keisuke Konosu, Yuji Okawa, Shono Shibuya +1
When we describe string field theory or quantum field theory in terms of homotopy algebras, on-shell scattering amplitudes at the tree level are obtained by the formula based on th…
Nonperturbative correlation functions from homotopy algebras
Keisuke Konosu, Yuji Okawa
The formula for correlation functions based on quantum algebras in arXiv:2203.05366, arXiv:2305.11634, and arXiv:2305.13103 requires us to divide the action into the fre…
Noether's theorem and Ward-Takahashi identities from homotopy algebras
Keisuke Konosu, Jojiro Totsuka-Yoshinaka
We derive the new identity in homotopy algebras which directly corresponds to the Schwinger-Dyson equations in quantum field theory. As an application, we derive the Ward-Takahashi…
