The author of this article deals with the eigenvalue problem for a uniformly elliptic operator with real coefficients defined on a bounded domain in \(\mathbb{R}^n\). The author shows that all the eigenvalues of the problem above belong to a certain set of \(\mathbb{C}\), which the author characterizes. The author also gives an example of a linear inverse problem with nonunique solutions.
