Abstract

The Kundu–Mukherjee–Naskar model is studied to reveal some vital optical solitons in (2[Formula: see text]+[Formula: see text]1) dimensions. To obtain singular soliton, dark soliton, combined dark-singular soliton and other hyperbolic solutions, we will use csch method, extended Tanh–Coth method and extended rational sinh-cosh method receptively with constraint conditions.
