"A fast numerical method for solving the Smoluchowski-type kinetic equations of aggregation and fragmentation processes"
Matveev S.A., Tyrtyshnikov E.E., Smirnov A.P., and Brilliantov N.V.

A number of models of aggregation-fragmentation processes on the basis of Smoluchowski-type kinetic equations are considered. A new numerical method for the fast solution of this class of problems is proposed. This method allows one to decrease the computational complexity of a problem without loss of accuracy. The application of the method is illustrated by several examples of problems of aggregation-fragmentation kinetics in the cases of interest in practice.

Keywords: Smoluchowski equation, kinetics equations of aggregation and fragmentation processes, predictor-corrector scheme, cross interpolation method, low-rank matrix approximations, discrete convolution.
