A numerical method for solving the Abel integral equation
A Haar wavelet operational matrix is applied to fractional integration, which has not been undertaken before. The Haar wavelet approximating method is used to reduce the fractional Volterra and Abel integral equations to a system of algebraic equations. A global error bound is estimated and some numerical examples with smooth, nonsmooth, and singular solutions are considered to demonstrate the validity and applicability of the developed method.
In this paper, the boundedness of the Riesz potential generated by generalized shift operator from the spaces to the spaces is examined.
