Approximate Wavelets and the Approximation
نویسنده
چکیده
The paper studies an approximate multiresolution analysis for spaces generated by smooth functions which provide high order cubature formulas for integral operators of mathematical physics. Since these functions satisfy reenement equations with any prescribed accuracy methods of the wavelet theory can be applied. We obtain a decomposition of the nest scale space into almost orthogonal wavelet spaces. For one example we study some properties of the analytic prewavelets, describe the projection operators onto the wavelet spaces and consider some applications to the cubature of integral operators.

In this paper, we use the continuous Legendre wavelets on the interval [0,1] constructed by Razzaghi M. and Yousefi S. [6] to solve the linear second kind integral equations. We use quadrature formula for the calculation of the products of any functions, which are required in the approximation for the integral equations. Then we reduced the integral equation to the solution of linear algebraic ...
