Abstract
We study a regularization of linear Volterra integral equation of the first kind with differentiable kernel degenerated at the initial point or at the end point of the interval on the diagonal. Accordingly, in the first case, the kernel on the diagonal is a non-decreasing function, in the second case, a non-increasing function. Regularizing Lavrentiev’s type operator is constructed that preserves the property of Volterra equation. We proved the uniform convergence of the regularized solution to the exact solution, and defined the conditions of uniqueness of the solution in the Holder space. We also considered the case of Volterra’s first kind linear integral equation with the approximated right hand side of equation. We established conditions under which a regularized solution to an equation with approximately given right-hand side can serve as an approximate solution to the original equation. The results can be used for numerical solution of the problem.中文翻译:
