Hierarchical N-body methods.
Abstract
The hierarchical tree method offers the possibility of computing the interaction between N self-gravitating particles in a time ≈ 0( N log N), without using a grid. The potential advantages of this technique for collisionless systems and for particle hydrodynamic schemes are discussed.
