Abstract

We propose an algorithm to find a solution to an integro-differential equation of the DGLAP type for all the orders in the running coupling α\alpha with splitting functions given at a fixed order in α.\alpha. Complex analysis is significantly used in the construction of the algorithm, we found a simpler way to calculate the involved integrals over contours in the complex planes than by any of the methods known at present.
