Abstract :
In this article, we use an effective coupled technique to solve singular integral equations with logarithmic kernel which it
occurs in different branches of sciences such as mathematical physics, mechanics, isotropic elastic, etc. At first, we
approximate the singular kernel by choosing suitable mesh points and multi-wavelet bases then, Galerkin method is used
for solving integral equations. In addition, for simplification and to achieve to a more accuracy, we convert integral
equation with logarithmic kernel to integro-differential equation with weakly singular kernel which is solvable with the
proposed method. The numerical results show the high accuracy of the solution.
