ESTIMATES OF THE QR-FACTORIZATION ELEMENTS IN SOLVING THE MATRICES IN THE WAVELET-GALERKIN METHOD

Some sums of mathematical physics allow natural generalization in the multidimensional singular equations which decision represents serious difficulties. The difficulty consist in that by the solution of such tasks we have the systems of the linear algebraic equations of high order; the special place is taken by a problem with the rarefied matrixes. In this article, the estimates of matrixes of QR factorization by the application of the wavelet-Galerkin method are considered.
