The number of Dirac-weighted eigenvalues of Sturm-Liouville equations with integrable potentials and an application to inverse problems
Xiao Chen, Jiangang Qi
In this paper, we further Meirong Zhang, et al.'s work by computing the number of weighted eigenvalues for Sturm-Liouville equations, equipped with general integrable potentials an…
KAM theorem for reversible mapping of low smoothness with application
Jing Li, Jiangang Qi, Xiaoping Yuan
Assume the mapping is reversible with respect to $G…
A priori bounds and existence of non-real eigenvalues of indefinite Sturm-Liouville problems
Jiangang Qi, Shaozhu Chen
The present paper gives a priori bounds on the possible non-real eigenvalues of regular indefinite Sturm-Liouville problems and obtains sufficient conditions for such problems to a…
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…
