As a method of approximation for the solution of partial differential equations the particle method has been used in fluid mechanics (particle in cell methods for the numerical computation of compressible multifluid flow and vortex methods of simulation of incompressible fluid flow at high Reynolds numbers), for the numerical solution of kinetic equations in physics (Boltzmann, Vlasov, and Fokker-Planck equations), and, more recently, in plasma physics.
A precise mathematical analysis of this numerical method has not been available until recently. These lectures consist of two chapters which provide a rigorous mathematical introduction to the particle method. The first chapter is devoted to the numerical solution of linear hyperbolic equations of the first order and contains unpublished results obtained by the author and G. H. Cottet. The second chapter deals with the vortex method for the Euler equations of incompressible perfect fluid flow and is based on the analysis given by O. Hald [SIAM J. Numer. Anal. 16, 726-755 (1979; Zbl 0427.76024)] as extended and improved by J. T. Beale and A. Majda [Math. Comput. 39, 1-27 (1982; Zbl 0488.76024) and ibid. 29-52 (1982; Zbl 0488.76025)] and by G. H. Cottet [Méthodes particulaires pour l’equation d’Euler dans le plans, Thèse de 3e cycle, Univ. P. et M. Curie, Paris (1982)]. Relevant references are given.
