چکیده

In this paper, we consider the initial value problem for mixed Schrödinger equation. For Schwartz data q0(x)∈S(R), by defining a general analytical domain and two reflection coefficients, ever found an unified long-time asymptotic formula via Deift–Zhou nonlinear steepest descent method. under essentially minimal regularity assumptions on in much weak weighted Sobolev space q0(x)∈H2,2(R), apply ∂̄ method to obtain asymptotics expression, leading order term O(t−1/2) comes from dispersive part qt + iqxx error O(t−3/4)

Long–time Asymptotics for Solutions of the Nls Equation with Initial Data in a Weighted Sobolev Space

Here Γ is the gamma function and the function r is the so-called reflection coefficient for the potential q0(x) = q(x, t = 0), as described below. The error term O( log t t ) is uniform for all x ∈ R. The above asymptotic form was first obtained in [ZaMa], but without the error estimate. Based on the nonlinear steepest descent method introduced in [DZ1], the error estimate in (1.1) was derived ...

Cauchy Problem of Nonlinear Schrödinger Equation with Initial Data in Sobolev Space W

In this paper, we consider in R the Cauchy problem for nonlinear Schrödinger equation with initial data in Sobolev space W s,p for p < 2. It is well known that this problem is ill posed. However, We show that after a linear transformation by the linear semigroup the problem becomes locally well posed in W s,p for 2n n+1 < p < 2 and s > n(1− 1 p ). Moreover, we show that in one space dimension, ...

Numerical solution for one-dimensional independent of time Schrödinger Equation

In this paper, one of the numerical solution method of one- particle, one dimensional timeindependentSchrodinger equation are presented that allows one to obtain accurate bound state eigenvalues and functions for an arbitrary potential energy function V(x).For each case, we draw eigen functions versus the related reduced variable for the correspondingenergies. The paper ended with a comparison ...
