Abstract

The properties of solutions of the equation u″(t) = p1 (t)u(τ1(t)) + p2(t)u′(τ2(t)) are investigated where pi: [a, +∞[→ R (i = 1, 2) are locally summable functions, τ1 : [a, +∞[→ R is a measurable function and τ2 : [a, +∞[→ R is a nondecreasing locally absolutely continuous one. Moreover, τi(t) ≥ t (i = 1, 2), p1 (t) ≥ 0, , ε = const > 0 and . In particular, it is proved that solutions whose derivatives are square integrable on [a, +∞ [ form a one-dimensional linear space and for any such solution to vanish at infinity it is necessary and sufficient that .
