In this work, a generalized time-dependent variable coefficients combined KdV-mKdV (Gardner) equation arising in plasma physics and ocean dynamics is studied. By means of three amplitude ansatz that possess modified forms to those proposed by Wazwaz in 2007, we have obtained the bell type solitary w
A generalized KdV equation with time-dependent coefficients will be studied. The BBM equation with time-dependent coefficients and linear damping term will also be examined. The wave soliton ansatz will be used to obtain soliton solutions for both equations. The conditions of existence of solitons a
The tanh method and the sine-cosine method are used for solving the fourth order nonlinear Schrodinger equations with cubic and power law nonlinearities. Several exact solutions with distinct structures are formally obtained for each type of nonlinearity. The study reveals the power of the two propo
