“…It is well known that many researchers have investigated the spectral properties of the Sturm-Liouville operator generated by the separate boundary condition (Aigunov, 1996) and many researchers have found asymptotic formula for the Sturm-Liouville operator's eigenvalues and functions in the case of periodic andanti-periodic boundary conditions (Menken, 2010;Naimark, 1967;Moller and Zinsou, 2012;Jwamer and Aigounv, 2010;Aigounov and Tamila, 2009;Aigunov, 1996 andTamarkin, 1928). Many researchers have been interested in the ongoing Sturm-Liouville issue in recent years as we see N.B.…”
