Symmetric ϵ- and (ϵ + 1/2)-forms and quadratic constraints in “elliptic” sectors.
Abstract Within the differential equation method for multiloop calculations, we examine the systems irreducible to ϵ-form. We argue that for many cases of such systems it is possible to obtain nontrivial quadratic constraints on the coefficients of ϵ-expansion of their homogeneous solutions. These c...
