摘要:
AbstractThe inhomogeneous mean‐field thermodynamic limit is constructed and evaluated for both the canonical thermodynamic functions and the states of systems of classical point particles with logarithmic interactions in two space dimensions. The results apply to various physical models of translation invariant plasmas, gravitating systems, as well as to planar fluid vortex motion. For attractive interactions a critical behavior occurs which can be classified as an extreme case of a second‐order phase transition. To include in particular attractive interactions a new inequality for configurational integrals is derived from the arithmetic‐geometric mean inequality. The method developed in this paper is easily seen to apply as well to systems with fairly general interactions in all space dimensions. In addition, it also provides us with a new proof of the Trudinger‐Moser inequality known from differential geometry – in its s
