Towards a categorification of scattering amplitudes
Severin Barmeier, Prafulla Oak, Aritra Pal +2
Categorification of scattering amplitudes for planar Feynman diagrams in scalar field theories with a polynomial potential is reported. Amplitudes for cubic theories are directly w…

Deformations of categories of coherent sheaves via quivers with relations
Severin Barmeier, Zhengfang Wang
We give an explicit combinatorial description of the deformation theory of the Abelian category of (quasi)coherent sheaves on any separated Noetherian scheme via the deformatio…

Learning scattering amplitudes by heart
Severin Barmeier, Koushik Ray
The canonical forms associated to scattering amplitudes of planar Feynman diagrams are interpreted in terms of masses of projectives, defined as the modulus of their central charge…
