Title: Integration-by-parts identities from module intersections

Abstract: We present the powerful module-intersection integration-by-parts (IBP) method, suitable for multi-loop and multi-scale Feynman integral reduction. Utilizing modern computational algebraic geometry techniques, this new method successfully trims traditional IBP systems dramatically to much simpler integral-relation systems on unitarity cuts. The cutting-edge IBP computation of non-planar 2-loop 5-point computation is presented.
