Author(s): Iris Bree, Federico Gasparotto, Antonela Matijašić, Pouria Mazloumi, Dmytro Melnichenko, Sebastian Pögel, Toni Teschke, Xing Wang, Stefan Weinzierl, Konglong Wu, and Xiaofeng Xu (ϵ Collaboration)We report on three improvements in the context of Feynman integral reduction and $ϵ$-factorized differential equations. First, we show that with a specific choice of prefactors, we trivialize the $ϵ$ dependence of the integration-by-parts identities. Second, we observe that with a specific ...
