Resumo: In this talk we present the local well-posedness of the initial value problem associated with the Scrödinger-Debye system posed on a $ d $-dimensional compact Riemannian manifold $ M $ for given data $ (u_{0},v_{0}) \in H^{s}(M)\times (H^{s}(M)\cap L^{\infty}(M)) $ whenever $ s>\frac{d}{2}-\frac12 $, $ d \geq 2 $. For $ d=2 $, we apply a sharp version of the Gagliardo-Nirenberg inequality in compact manifold to derive an a $ priori $ estimate for the $ H^{1} $-solution and use it to prove the global well-posedness result in this space.
