报告摘要:We study a class of semi-linear elliptic systems of Gross-Pitaevskii type with Dirichlet boundary conditions, and prove that uniform boundedness of the solutions implies their uniform global Lipschitz boundedness as the competition constant goes to infinity, this improves interesting uniform Holder regularity results of Terracini et al.(CPAM, 2010) to the optimal case and cover the one dimension case, here the space dimension can be arbitrary and the domain can be unbounded. We also obtain the uniform interior Lipschitz bounds of the solutions, and develop the result of Soave and Zilio (ARMA, 2015) in a general setting. The proofs are based on blow-up analysis and Alt-Caffarelli-Friedman type monotonicity formulae both in the domain and near the domain boundary(joint with Zexin Zhang).
