In this paper, we present some results of the application of the projection method of least squares for the search for the first- and second-order moment functions of the solution of the two-dimensional equation of exciton diffusion with a random coefficient. An estimate of the error for the quadratic functional is obtained. Results of computational experiments for the parameters characteristic of gallium nitride are presented.
Mots-clés : diffusion equation, Laguerre functions
Keywords: projection method of least squares, expectation, autocorrelation function, modulus of continuity.
