Anderson, Douglas R. Oscillation and nonoscillation criteria for two-dimensional time-scale systems of first-order nonlinear dynamic equations. (English) Zbl 1185.34140 Electron. J. Differ. Equ. 2009, Paper No. 24, 13 p. (2009). The author extends oscillation criteria for certain two-dimensional linear difference and differential systems of first-order to nonlinear dynamic equations on arbitrary time scales. An example is presented to show that a key theorem is sharp on all time scales.
