Oscillation criteria for second order linear equations on a time scale. (English) Zbl 1050.39024

Summary: We apply averaging techniques to develop oscillation criteria for the second order scalar differential equation \((r(t) x^\Delta(t))^\Delta+ q(t) x^\sigma(t)=0\), on a time scale (measure chain) \(\mathbb{T}\). These results extend some earlier criteria for the differential and difference equation case.
