| 英文摘要 | In this paper, we consider the large deviations principles (LDPs) for the stochastic linear Schrodinger equation and its symplectic discretizations. These numerical discretizations are the spatial semi-discretization based on the spectral Galerkin method, and the further full discretizations with symplectic schemes in temporal direction. First, by means of the abstract Gartner-Ellis theorem, we prove that the observable B-T = u(T)/T, T > 0 of the exact solution u is exponentially tight and satisfies an LDP on L-2(0, pi; C). Then, we present the LDPs for both {B-T(M)}(T>0 )of the spatial discretization {u(M)}(M is an element of N) and {B-N(M)}(N is an element of N) of the full disum cretization {u(N)(M)}(M,N is an element of N), where B-T(M) = u(M)(T)/T and B-N(M) = u(N)(M)/N-tau are the discrete approximations of B-T. Further, we show that both the semi-discretization {u(M)}(M is an element of N) and the full discretization {u(N)(M)}(M,N is an element of N) based on temporal symplectic schemes can weakly asymptotically preserve the LDP of {B-T}(T>0). These results show the ability of symplectic discretizations to preserve the LDP of the stochastic linear Schrodinger equation, and first provide an effective approach to approximating the large deviations rate function in infinite dimensional space based on the numerical discretizations. |
