✦ Synopsis
We have investigated the viscosity (the angular momentum flux) in dense, self-gravitating particle disks such as Saturn's main ring, by performing local N-body simulations. Viscosity could play important roles in evolution and structure formation of planetary rings. The ring's viscosity has been investigated with both theoretical and numerical approaches (e.g., Goldreich and Tremaine, 1978,
