r831548 rbdfe704 9 9 OVERVIEW: 10 10 This Library implements an algorithm based on the work of E. K. Leinartas to 11 write rational functions in mu tiple variables as a sum of functions with11 write rational functions in multiple variables as a sum of functions with 12 12 \"smaller\" numerators and denominators. 13 This can be used to shorten the IBP reduction coeff cients of multi-loop Feynman13 This can be used to shorten the IBP reduction coefficients of multi-loop Feynman 14 14 integrals. For this application, 15 15 we also provide a procedure that applies the algorithm to all entries of a … … 472 472 } 473 473 474 ideal q_denom = q[indices]; // factors occur ing in the denominator474 ideal q_denom = q[indices]; // factors occurring in the denominator 475 475 matrix T; 476 476 ideal q_std = liftstd(q_denom,T);
