Kinetic theory of point vortex systems from the Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy.
Kinetic equations are derived from the Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy for point vortex systems in an infinite plane. At the level of approximation for the Landau equation, the collision term of the kinetic equation derived coincides with that by Chavanis [Phys. Rev. E 64, 026309 (2001)]. Furthermore, we derive a kinetic equation corresponding to the Balescu-Lenard equation for plasmas using the theory of the Fredholm integral equation. For large N , this kinetic equation is reduced to the Landau equation above.
