Synchronization of spatiotemporal chaos with positive conditional Lyapunov exponents

摘要: Computer simulations show that, following the scalar driving approach, synchronization of spatiotemporal chaos can also be achieved in driven subsystem with positive conditional Lyapunov exponents. This is a result so-called extreme trap. In neighborhood maximum value, higher-order term difference causes first-order dissipative effect, which not reflected by Hence actual average divergence rate smaller than number and thus system to synchronize even when exponents are positive.
