Feynman Integral Reduction without Integration-By-Parts
Ziwen Wang, Li Lin Yang
We present an interesting study of Feynman integral reduction that does not employ integration-by-parts identities. Our approach proceeds by studying the equivalence relations of i…

Feynman integral reduction with intersection theory made simple
Li-Hong Huang, Yan-Qing Ma, Ziwen Wang +1
Feynman integral reduction based on intersection theory provides an alternative to the traditional integration-by-parts method, yet its practical application has been constrained b…

Intersection theory, relative cohomology and the Feynman parametrization
Mingming Lu, Ziwen Wang, Li Lin Yang
We present a novel approach for loop integral reduction in the Feynman parametrization using intersection theory and relative cohomology. In this framework, Feynman integrals corre…
