Dd. Bainov et al., STABILITY OF THE NOTION OF DICHOTOMY OF LINEAR IMPULSIVE DIFFERENTIAL-EQUATIONS IN A BANACH-SPACE, Indian Journal of Pure and Applied Mathematics, 26(4), 1995, pp. 321-328
In this paper sufficient conditions for stability of the ordinary and
exponential dichotomy of impulsive equations under small perturbations
of the points of impulse effect are obtained.
