Solvability Criterion for Linear Boundary-value Problems for Integral Equations with Nondegenerate Kernel in Hilbert Spaces
摘要
By using the general theory of pseudoinverse operators and orthoprojectors, we construct an operator pseudoinverse to an integral operator with nondegenerate kernel and establish criteria for the solvability of integral equations with nondegenerate kernels and boundary-value problems for these equations in Hilbert spaces.
