Some oscillation theorems for second order differential equations

Chung-Fen Lee, Cheh Chih Yeh, Chuen-Yu Gau (2005)

Czechoslovak Mathematical Journal

In this paper we establish some oscillation or nonoscillation criteria for the second order half-linear differential equation ${(r (t) Φ (u^{'} (t)))}^{'} + c (t) Φ (u (t)) = 0,$ where (i) $r, c \in C ([t_{0}, \infty)$ , $ℝ : = (- \infty, \infty))$ and $r (t) > 0$ on $[t_{0}, \infty)$ for some $t_{0} \geq 0$ ; (ii) $Φ (u) = {| u |}^{p - 2} u$ for some fixed number $p > 1$ . We also generalize some results of Hille-Wintner, Leighton and Willet.

Some properties of third order differential operators

Mariella Cecchi, Zuzana Došlá, Mauro Marini (1997)

Czechoslovak Mathematical Journal

Consider the third order differential operator $L$ given by $L (\cdot) \equiv \frac{1}{a_{3} (t)} \frac{d}{d t} \frac{1}{a_{2} (t)} \frac{d}{d t} \frac{1}{a_{1} (t)} \frac{d}{d t} (\cdot)$ and the related linear differential equation $L (x) (t) + x (t) = 0$ . We study the relations between $L$ , its adjoint operator, the canonical representation of $L$ , the operator obtained by a cyclic permutation of coefficients $a_{i}$ , $i = 1, 2, 3$ , in $L$ and the relations between the corresponding equations. We give the commutative diagrams for such equations and show some applications (oscillation, property A).
