【 摘 要 】

We prove the existence of solutions (lambda, v) is an element of R x H-1(Omega) of the elliptic problem {-Lambda nu + (V(x)+ lambda)nu = nu(p) in Omega, nu > 0, integral(nu 2)(Omega) dx = rho. Any vsolving such problem (for some lambda) is called a normalized solution, where the normalization is settled in L-2(Omega). Here Omega is either the whole space R-N or a bounded smooth domain of R-N, in which case we assume V equivalent to 0 and homogeneous Dirichlet or Neumann boundary conditions. Moreover, 1 < p < N+2/N- 2 if N >= 3 and p > 1 if N = 1, 2. Normalized solutions appear in different contexts, such as the study of the Nonlinear Schrodinger equation, or that of quadratic ergodic Mean Field Games systems. We prove the existence of solutions concentrating at suitable points of Omega as the prescribed mass rho is either small (when p< 1 + 4/N) or large (when p = 1 + 4N) or it approaches some critical threshold (when p = 1 + 4N).
