Title: On an inequality by N. Trudinger and J. Moser and related elliptic equations

Abstract: It has been shown by Trudinger and Moser that for normalized functions u of the Sobolev space W-1,W-N (Omega), where Omega is a bounded domain in R-N, one has integral (Omega) exp(alpha (N)\u\(N/(N-1)))dx less than or equal to C-N, where alpha (N) is an explicit constant depending only on N, and C-N is a constant depending only on N and Omega. Carleson and Chang proved that there exists a corresponding extremal function in the case that Omega is the unit ball in R-N. In this paper we give a new proof, a generalization, and a new interpretation of this result. In particular, we give an explicit sequence that is maximizing for the above integral among all normalized "concentrating sequences." As an application, the existence of a nontrivial solution for a related elliptic equation with "Trudinger-Moser" growth is proved. (C) 2002 John Wiley & Sons, Inc.
