Description
Summary:The main attention of this work focus on finding solitary wave solutions for the variable-coefficient nonlinear Schrödinger equation with an external potential. Here, we analytically derived bright soliton, dark soliton, periodic soliton as well as triangular soliton through the complete discrimination system. Particularly, the Cross-shaped and T-shaped dark soliton are demonstrated.
