Relative Oscillation Theory for Sturm-Liouville Operators Extended

Helge Krueger, Gerald Teschl

We extend relative oscillation theory to the case of Sturm--Liouville operators with different 's. We show that the weighted number of zeros of Wrons…

Relative Oscillation Theory, Weighted Zeros of the Wronskian, and the Spectral Shift Function

Helge Krueger, Gerald Teschl

We develop an analog of classical oscillation theory for Sturm-Liouville operators which, rather than measuring the spectrum of one single operator, measures the difference between…
