HOMOTOPY PERTURBATION METHOD AND CHEBYSHEV POLYNOMIALS FOR SOLVING A CLASS OF SINGULAR AND HYPERSINGULAR INTEGRAL EQUATIONS

摘要

In this note, we review homotopy perturbation method (HPM), Discrete HPM, Chebyshev polynomials and its properties. Moreover, the convergences of HPM and error term of Chebyshev polynomials were discussed. Then, linear singular integral equations (SIEs) and hyper-singular integral equations (HSIEs) are solved by combining modified HPM together with Chebyshev polynomials. Convergences of the mixed method for the linear HSIEs are also obtained. Finally, illustrative examples and comparisons with different methods are presented.
