摘要：
We prove a sharp dispersive estimate vertical bar P(ac)u(t, x)vertical bar <= C vertical bar t vertical bar(-1/2) . vertical bar vertical bar u(0)vertical bar vertical bar L(1(R)) for the one dimensional Schrodinger equation iu(t) - u(xx) + V (x)u + V(0)(x) = 0, where (1 + x(2))V E is an element of L(1) (R) and V(0) is a step function, real valued and constant on the positive and negative real axes.
