摘要：
We investigate the presence of localized analytical solutions of the Schrodinger equation with logarithm nonlinearity. After including inhomogeneities in the linear and nonlinear coefficients, we use similarity transformation to convert the nonautonomous nonlinear equation into an autonomous one, which we solve analytically. In particular, we study stability of the analytical solutions numerically. (C) 2014 Elsevier B. V. All rights reserved.
