Applying Gröbner Bases to Solve Reduction Problems for Feynman Integrals

چکیده

We describe how Gröbner bases can be used to solve the reduction problem for Feynman integrals, i.e. to construct an algorithm that provides the possibility to express a Feynman integral of a given family as a linear combination of some master integrals. Our approach is based on a generalized Buchberger algorithm for constructing Gröbner-type bases associated with polynomials of shift operators. We illustrate it through various examples of reduction problems for families of oneand two-loop Feynman integrals. We also solve the reduction problem for a family of integrals contributing to the three-loop static quark potential. E-mail: [email protected] E-mail: [email protected]

ar X iv : h ep - p h / 06 06 24 7 v 1 2 2 Ju n 20 06 S - bases as a tool to solve reduction problems for Feynman integrals

We suggest a mathematical definition of the notion of master integrals and present a brief review of algorithmic methods to solve reduction problems for Feynman integrals based on integration by parts relations. In particular, we discuss a recently suggested reduction algorithm which uses Gröbner bases. New results obtained with its help for a family of three-loop Feynman integrals are outlined.

Gröbner Bases Applied to Systems of Linear Difference Equations

In this paper we consider systems of partial (multidimensional) linear difference equations. Specifically, such systems arise in scientific computing under discretization of linear partial differential equations and in computational high energy physics as recurrence relations for multiloop Feynman integrals. The most universal algorithmic tool for investigation of linear difference systems is b...

Computation of Gröbner Bases for Two-Loop Propagator Type Integrals

The most efficient algorithms to evaluate Feynman diagrams exploit recursive methods based on integration by parts technique [2] or technique of generalized recurrence relations [3], [4]. It is easy to derive hundreds of recurrence relations but it is by far not so easy to formulate optimal algorithm how to use them for the reduction of a given type of integrals to a minimal set of basis integr...

Algorithm FIRE — Feynman Integral REduction

The recently developed algorithm FIRE performs the reduction of Feynman integrals to master integrals. It is based on a number of strategies, such as applying the Laporta algorithm, the s-bases algorithm, region-bases and integrating explicitly over loop momenta when possible. Currently it is being used in complicated three-loop calculations. Supported by RFBR grant 08-02-01451-a and DFG throug...

A Maple Package for Computing Gröbner Bases for Linear Recurrence Relations

A Maple package for computing Gröbner bases of linear difference ideals is described. The underlying algorithm is based on Janet and Janet-like monomial divisions associated with finite difference operators. The package can be used, for example, for automatic generation of difference schemes for linear partial differential equations and for reduction of multiloop Feynman integrals. These two po...
