Exact optical solutions of the (2 + 1) dimensions Kundu-Mukherjee-Naskar model via the new extended direct algebraic method

In this work, the researchers for computing an exact solution of the (2+1) dimensions Kundu-Mukherjee-Naskar (KMN) equation used a newly developed technique, namely, the new extended direct algebraic method. This powerful method gives an exact solution to the KMN equation considered in this paper. The results are new and attest to the efficiency of the proposed method. © 2020 World Scientific Publishing Company.
