摘要 研究了各向异性的Schrdinger方程iut+Δu+aux1x1x1x1+bux1x1x1x1x1x1+|u|αu=0的初值问题的整体可解性,其中a,b都是实常数,α是正常数。选取合适的p=2(α|2)/αs+2,利用非线性项|u|αu的估计和各向异性的Schrdinger算子S(t)的Lp'-Lp估计,以及利用Banach不动点定理,获得了整体(几乎整体)解在Es(ETs0)中的存在性。 Global solvability of initial value problem for the non-isotropic Schrodinger equation : iut+△u+aux|x|x|+bux|x|x|x|x|x+|u|αu =0(where a, b О∈ R ,a 〉 0) is studied. Take p=2(a+2)/as+2By using the nonlinear esti-mate of | u |a u , the L^p - L^p estiamte of the non - isotropic Schrodinger operator S(t) and Banach fixed point theorem, the exisitence of global ( almost global) solution in Es ( E^sT0) is obtained.
