Abstract
Nonlinear dynamics of vortices in high-J(c) overdamped Josephson conta cts with time-dependent transport current J(t) is considered. It is sh own that equations of nonlocal Josephson electrodynamics which describ e an Abrikosov vortex with Josephson core can be solved exactly for an y J(t). Different nonlinear regimes, such as vortex acceleration after a stepwise change of J(t) and oscillations of a vortex for periodic A C currents are calculated analytically.
