Estimates on the non-real eigenvalues of regular indefinite Sturm-Liouville problems
Jussi Behrndt, Shaozhu Chen, Friedrich Philipp +1
Regular Sturm-Liouville problems with indefinite weight functions may possess finitely many non-real eigenvalues. In this note we prove explicit bounds on the real and imaginary pa…
