Eigenvalue problem of Sturm-Liouville systems with separated boundary conditions

Xijun Hu, Penghui Wang

Let $λ_{j}$ be the $j$ -th eigenvalue of Sturm-Liouville systems with separated boundary conditions, we build up the Hill-type formula, which represent $j \prod (1 - λ_{j}^{- 1})$ …

Hill-type formula and Krein-type trace formula for $S$ -periodic solutions in ODEs

Xijun Hu, Penghui Wang

The present paper is devoted to studying the Hill-type formula and Krein-type trace formula for ODE, which is a continuous work of our previous work for Hamiltonian systems \cite{H…
