We investigate oscillation of second-order half-linear variable delay damped dynamic equationson a time scale T. By using the generalized Riccati transformation and the inequality technique, we establish some new oscillation criteria for the equations under the conditionThese results deal with some cases not covered by existing results in the literature.and right-scattered if σ (t) > t. The graininess μ of the time scale is defined by μ(t) = σ (t)-t. For a function f : T → R, the (delta) derivative is defined by f (t) = f (σ (t))-f (t) σ (t)-t © The Author(s) 2019.
