Stability in Terms of Two Measures for Nonlinear Impulsive Systems on Time Scales

We investigate some stability problems in terms of twomeasures for nonlinear dynamic systems on time scales with fixedmoments of impulsive effects. Sufficient conditions for (uniform) stability, (uniform) asymptotic stability, and instability in terms of two measures are derived by using the method of Lyapunov functions. Our results include the existing results as special cases when the time scale reduces to the set of real numbers. Particularly, our results provide stability criteria for impulsive discrete systems in terms of two measures, which have not been investigated extensively. Two examples are presented to illustrate the efficiency of the proposed results.
