Resumo

We consider the inhomogeneous biharmonic nonlinear Schrodinger equation (IBNLS) iu(t) +Delta(2)u +lambda vertical bar x vertical bar(-b)vertical bar u vertical bar(alpha) u = 0, where lambda = +/- 1 and alpha, b > 0. We show local and global well-posedness in H-s(R-N) in the H-s-subcritical case, with s = 0, 2. Moreover, we prove a stability result in H-2(R-N), in the mass-supercritical and energy-subcritical case. The fundamental tools to prove these results are the standard Strichartz estimates related to the linear problem. (C) 2020 Elsevier Ltd. All rights reserved. (AU)
