Title 



Differential correction algorithm for a function of two continuous variables : application to the collision integrals


Author 





Abstract 



The differential correction algorithm is a wellknown algorithm for finding a rational approximating function to a function on one discrete or continuous variable. In this work we present a modification of the differential correction algorithm using (quasirandom) Korobov points in order to apply it to functions of two continuous variables. The algorithm is applied to the lowenergy ionscattering (LEIS) collision integrals. The approximation obtained is more accurate and about one order of magnitude faster than other approximations in the literature.
