Factorization of denominators as a `fuel' for Feynman integral reduction
Alexander V. Smirnov, Vladislav. A. Fokin, Egor Yu. Chuvashov
Rational-function simplification is key bottlenecks in integration-by-parts (IBP) reduction of Feynman integrals. We study denominator factorization patterns appearing in IBP coeff…
GPU Implementation of Zippel Method for Feynman Integral Reconstruction
Alexander V. Smirnov, Boris I. Rozhnov, Vadim V. Voevodin
The Zippel algorithm performs a rational reconstruction of multivariate polynomials and aims specifically at the sparse case. It is applied in different fields of science, lately b…
Efficient reduction of Feynman integrals on supercomputers
A. V. Belitsky, A. A. Kokosinskaya, A. V. Smirnov +2
Feynman integral reduction by means of integration-by-parts identities is a major power gadget in a theorist toolbox indispensable for calculation of multiloop quantum effects rele…
FIESTA5: numerical high-performance Feynman integral evaluation
A. V. Smirnov, N. D. Shapurov, L. I. Vysotsky
In this paper we present a new release of the FIESTA program (Feynman Integral Evaluation by a Sector decomposiTion Approach). FIESTA5 is performance-oriented - we implemented impr…
FIESTA 4: optimized Feynman integral calculations with GPU support
Alexander V. Smirnov
This paper presents a new major release of the program FIESTA (Feynman Integral Evaluation by a Sector decomposiTion Approach). The new release is mainly aimed at optimal performan…
