摘要：In this report, we introduce the some new results for the Schrodinger operator on the half line. In the Part I, we introduce the stability of direct and inverse scattering problems. For the direct problem, we give the estimates for the difference of the reflection coefficients in terms of the differences of the corresponding potentials and the parameters in the boundary conditions; for the inverse problem, we give the estimates for the difference of the potentials in terms of the difference of the corresponding scattering data. In the Part II, we introduce the transmission eigenvalue problem with the Robin boundary condition. For the direct problem, we give the density and the asymptotics of the transmission eigenvalues; for the inverse problem, we introduce some uniqueness theorems for recovering the potential from the transmission eigenvalues.
