(Twisted) canonical supermultiplets and their resolutions as open-closed homotopy algebras
Simon Jonsson
We argue that some supersymmetric multiplets can naturally be equipped with the structure of an open-closed homotopy algebra. This structure is readily described through the pure s…

Homotopy representations of extended holomorphic symmetry in holomorphic twists
Simon Jonsson, Hyungrok Kim, Charles Alastair Stephen Young
We argue that holomorphic twists of supersymmetric field theories naturally come with a symmetry -algebra that nontrivially extends holomorphic symmetry. This symmetry ac…

Out-of-time-order asymptotic observables are quasi-isomorphic to time-ordered amplitudes
Leron Borsten, Simon Jonsson, Hyungrok Kim
Asymptotic observables in quantum field theory beyond the familiar -matrix have recently attracted much interest, for instance in the context of gravity waveforms. Such observab…
