OSCILLATION CRITERIA FOR SECOND ORDER
LINEAR EQUATIONS ON A TIME SCALE
Abstract. We apply averaging techniques to develop oscillation
criteria for the second order scalar differential equation
(r(t)xΔ(t))Δ + q(t)xσ(t) = 0, on a time scale (measure
chain) T. These results extend some earlier criteria for the
differential and difference equation case.
