On the zeros of solutions of nonhomogeneous third order differential equations. (English) Zbl 0758.34022

Czech. Math. J. 41(116), No. 4, 641-652 (1991).
The comparison of the oscillatory and nonoscillatory behaviour of the solutions to the differential equation \((r(t)y'')'+q(t)y'+p(t)y=f(t)\) and its associated homogeneous equation as well as some related problems are studied. Here \(p,q,r,f\in C([0,\infty),\mathbb{R})\) and \(r(t)>0\).
