Integrability from Homotopy Algebras
Luigi Alfonsi, Leron Borsten, Mehran Jalali Farahani +3
Homotopy algebraic methods have become increasingly influential in studying field theories. We consider semi-holomorphic Chern-Simons theory and its relation with the principal chi…
Extremal Black Holes from Homotopy Algebras
Jan Gutowski, Chettha Saelim, Martin Wolf
The uniqueness and rigidity of black holes remain central themes in gravitational research. In this work, we investigate the construction of all extremal black hole solutions to th…
Field Theory Equivalences as Spans of -algebras
Mehran Jalali Farahani, Christian Saemann, Martin Wolf
Semi-classically equivalent field theories are related by a quasi-isomorphism between their underlying -algebras, but such a quasi-isomorphism is not necessarily a homoto…
Adjusting Higher Chern-Simons Theory
Gianni Gagliardo, Dominik Rist, Christian Saemann +1
A fundamental problem in formulating higher Chern-Simons theories is the construction of a consistent higher gauge theory that circumvents the fake-flatness constraint. Here, we pr…
Ambitwistor Yang-Mills Theory Revisited
Leron Borsten, Branislav Jurco, Hyungrok Kim +2
Inspired by the Movshev-Mason-Skinner Cauchy-Riemann (CR) ambitwistor approach, we provide a rigorous yet elementary construction of a twisted CR holomorphic Chern-Simons action on…
Full S-matrices and Witten diagrams with (relative) L-infinity algebras
Luigi Alfonsi, Leron Borsten, Hyungrok Kim +2
The -algebra approach to scattering amplitudes elegantly describes the nontrivial part of the -matrix but fails to take into account the trivial part. We argue that th…
