Oscillation and spectral properties of self-adjoint even order differential operators with middle terms
Oscillation and spectral properties of even order self-adjoint differential operators of the form $$ L(y):=\frac{1}{w(t)}\sum_{k=0}^n (-1)^k \left(r_k(t)y^{(k)}\right)^{(k)},\quad r_n(t)>0\, ,w(t)>0, %\tag{L} $$ are investigated. A particular attention is devo...
