We consider not necessarily self-adjoint differential operators generated by ordinary differential expressions of the form My= f: pi(t)y"' on Z=[l, co) (\*) i=O with n = ord(M) E N, pi E ci(Z, C).

Oscillation and spectral properties of the one-term differential operator of the form are investigated. It is shown that certain recently established necessary conditions for discreteness a boundedness below of the spectrum of 1 are also sufficient for this property. Some related problems are also i

In this article, we consider an operator L defined by the differential expression l l y s yy Y q q x y, we have proved a spectral expansion of L in terms of the principal functions, taking into account the spectral singularities. We have also investigated the convergence of the spectral expansion o
