Nieto We present some new nonlinear integral inequalities Bellman-Bihari type with delay for discontinuous functions integro-sum inequalities impulse integral inequalities . Some applications of the results are included conditions of boundedness uniformly stability by Lyapunov uniformly practical stability by Chetaev uniformly for the solutions of impulsive differential and integrodifferential systems of ordinary differential equations.
