摘要：

We solve the operator equation , where A and B are closed operators whose point spectra intersect. We obtain sufficient conditions for the existence of solutions and provide a way of constructing them. As a corollary, we obtain a result that gives us new insight on the matrix equations of the form , where A and B share non-zero eigenvalues. Afterwards, we illustrate our results on Sturm-Liouville operators.
