In the field of maritime transport,motion and energy,the dynamics of deep-sea waves is one of the major problems in ocean science.A mathematical modeling of dynamics of solitary waves in deep sea under the two-layer stratification leads to NLS equation,and consequently,the interaction two of them can be formulated by coupled NLS *** this work,extended auxiliary equation and the exp(−ω(χ))-expansion methods are employed to make the optical solutions of the Manakov model of coupled NLS *** methods used in this paper,in addition to providing the analysis of individual wave solutions,also provide general optical *** previously known solutions can be obtained by some special selections of parameters obtained by solving systems of algebraic *** this stage,it is more practical and convenient to apply methods with a symbolic calculation system.
