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…
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…
Trivalent Feynman Diagrams as a Flag
Lili Yang
By identifying each standard flag with a trivalent Feynman diagram, the corresponding propagators can be read directly from the flag itself. Within the flag representation, the kin…
Symbol letters of Feynman integrals from Gram determinants
Xuhang Jiang, Jiahao Liu, Xiaofeng Xu +1
Symbol letters are crucial for analytically calculating Feynman integrals in terms of iterated integrals. We present a novel method to construct the symbol letters for a given inte…
