Canonical differential equations for the elliptic two-loop five-point integral family relevant to jet production at leading colour
Matteo Becchetti, Christoph Dlapa, Simone Zoia
We present differential equations (DEs) in canonical form for a family of two-loop five-point Feynman integrals containing elliptic functions and nested square roots. This is the o…

A differential-geometry approach to operator mixing in massless QCD-like theories and Poincaré-Dulac theorem
Matteo Becchetti
We review recent progress on operator mixing in the light of the theory of canonical forms for linear systems of differential equations and, in particular, of the Poincaré-Dulac th…
