Integral Equations: Theories, Approximations, and Applications.

This special issue collects innovative contributions addressing the top challenges in integral equations, integro-differential equations, multi dimensional problems, and ill-posed and singular problems with modern applications. Linear and nonlinear integral equations of the first and second kinds have many applications in engineering and real life problems. Brief Overview of the Contributions Ibrahimov and Imanova in "Multistep Methods of the Hybrid Type and Their Application to Solve the Second Kind Volterra Integral Equation" [[1]] have focused on solving the integral equations with variable boundaries. Noeiaghdam et al. have focused on "Error Estimation of the Homotopy Perturbation Method to Solve Second Kind Volterra Integral Equations with Piecewise Smooth Kernels: Application of the CADNA Library" in [[9]].
