Abstract
This study devoted to the investigation of comparison properties for
periodic Sturm-Liouville problems, defined on three disjoint intervals together with
additional transfer conditions across the common endpoint of these intervals, so-called
transmission conditions. The results obtained generalize the corresponding
classical results of Sturm's comparison and oscillation theory.
