Oscillation of the second order advanced differential equations

We establish a new technique for deducing oscillation of the second order advanced differential equation \begin{equation*} \left(r(t)u'(t)\right)'+p(t)u(\sigma(t))=0 \end{equation*} with help of a suitable equation of the form $$ \left(r(t)u'(t)\right)'+q(t)u(t)=0. $$ The compa...
