讨论一类带白噪声的随机非线性Schrodinger方程,通过建立方程的性质,运用随机分析方法和Gagliardo-Nirenberg不等式,得到了该方程所对应的初值问题整体解存在的一个充分条件,该条件与一个非线性数量场方程的基态解有关,推广了确定性非线性Schrodinger方程在随机情形下的结论.
In this paper,the stochastic nonlinear Schrodinger equation with white noise is discussed.By using stochastic analysis and the Gagliardo-Nirenberg inequality,a sufficient condition for solutions to globally exist is derived.This condition is in terms of the ground state solution of a nonlinear scalar field equation.Some results for determined nonlinear Schrodinger equation in stochastic case are generalized.
