The results of a numerical study on the influence of topological defects on mass transfer processes are presented for two-dimensional nonideal systems. Calculations have been performed for Yukawa and inverse-power potentials in a wide range of parameters, corresponding to the experimental conditions in the laboratory dusty plasmas. The relations between a number of topological defects and diffusion coefficients for interacting particles are obtained for the first time.
