摘要
The present paper deals with non-real eigenvalues of nonlocal indefinite Sturm-Liouville problems involving nonlocal potential terms associated to nonlocal coupled boundary conditions. A priori bounds on the imaginary parts and absolute values of these non-real eigenvalues in terms of the coefficients of the differential expression are obtained.
