Self-duality from twisted cohomology
Claude Duhr, Franziska Porkert, Cathrin Semper +1
Recently a notion of self-duality for differential equations of maximal cuts was introduced, which states that there should be a basis in which the matrix for an ε-factorised diffe…

Twisted Riemann bilinear relations and Feynman integrals
Claude Duhr, Franziska Porkert, Cathrin Semper +1
Using the framework of twisted cohomology, we study twisted Riemann bilinear relations (TRBRs) satisfied by multi-loop Feynman integrals and their cuts in dimensional regularisatio…
