摘要：In this talk we will present a new spectral method fora class of equations with non-smooth solutions. The proposed method makes use of the fractional polynomials, also knownas Muntz polynomials. We first present some basic approximation properties of the Muntz polynomials, including error estimates for the weighted projection and interpolation operators. Then we will show how to constructefficient spectral methods by using the Muntz polynomials.A detailed convergence analysis will be provided.The potential application of this method coversa large number of problems, including classical elliptic equations,integro-differential equations with weaklysingular kernels, fractional differential equations, and so on.
