Abstract: The authors propose an effective evolution equation for a coarse-grained distribution function of a long-range-interacting system preserving the symplectic structure of the Vlasov equation valid at the fine-grained level. Symmetry considerations suggest a general form of the evolution equation, that is then explicitly derived in the case of one-dimensional systems. The equation predicts how the damping times depend on the coarse-graining scale.
