• Resumen

  • We consider the uniqueness of solutions of the equation ?2u = eu in four-dimensional Euclidean space. Our main result is that the solutions are all classical ones, provided that the energy of the solutions is finite and the diffusion of the solutions decays to zero at infinity. The method we used in this paper is known as the method of moving spheres.
