TY - JOUR AU - Delanoƫ, Philippe PY - 2002/09/01 Y2 - 2024/03/29 TI - Perturbing fully nonlinear second order elliptic equations JF - Topological Methods in Nonlinear Analysis JA - TMNA VL - 20 IS - 1 SE - DO - UR - https://apcz.umk.pl/TMNA/article/view/TMNA.2002.025 SP - 63 - 75 AB - We present two types of perturbations with reverse effectson some scalar fully nonlinear second order elliptic differentialoperators: on the other hand, first order perturbations which destroy the global solvability of the Dirichlet problem, in smooth bounded domains of $\mathbb R^n$;on the other hand, an integral perturbation which restore the local solvability, on compact connected manifolds without boundary.
