Oscillation of fourth-order dynamic equations. (English) Zbl 1228.34145
The authors study oscillation of all solutions of a nonlinear fourth order dynamic equation by comparing it with second order dynamic equations. Oscillation of these second order equations yields oscillation of the studied equation.
