NONLINEAR DYNAMICS, cilt.87, sa.3, ss.1973-1984, 2017 (SCI-Expanded)
Non-autonomous grazing phenomenon is investigated through periodic systems and their solutions. The analysis is different than for autonomous systems in many aspects. Conditions for the existence of a linearization have been found. Stability of a periodic solution and its persistence under regular perturbations are investigated. Through examples, the theoretical results are visualized.
