Oscillation criteria for fourth-order nonlinear delay dynamic equations
Electronic journal of differential equations, Tome 2013 (2013)
We obtain criteria for the oscillation of all solutions to a fourth-order nonlinear delay dynamic equation on a time scale that is unbounded from above. The results obtained are illustrated with examples
