The main focus of this research is on finding solitary wave solutions for the variable coefficient nonlinear Schrodinger equation with an external potential, including bright soliton, dark soliton, periodic soliton, and triangular soliton derived through the complete discrimination system. Particularly, the Cross-shaped and T-shaped dark soliton are demonstrated.
