Parametric oscillators from factorizations employing a constant-shifted Riccati solution of the harmonic oscillator

H. C. Rosu, K. V. Khmelnytskaya

We determine the kind of parametric oscillators that are generated in the usual factorization procedure of second-order linear differential equations when one introduces a constant…

Spectral parameter power series representation for Hill's discriminant

K. V. Khmelnytskaya, H. C. Rosu

We establish a series representation of the Hill discriminant based on the spectral parameter power series (SPPS) recently introduced by V. Kravchenko. We also show the invariance…
