Extended exp(−φ (ξ))-expansion method for generalized breaking soliton equation

Here, an extended version of the lionized KdV equation known as generalized breaking soliton equation in (1 + 3)-dimensions has been examined. Exact solutions for the considered are scrutinized by incorporating an effective approach namely; extended exp(−φ (ξ))-expansion method. Rational, hyperbolic function, trigonometric function solutions with arbitrary constants are determined by applying the above mentioned method. The obtained exact solutions are completely new as extended exp(−φ (ξ))-expansion method or any equivalent scheme of this method has never been engaged in the literature along with the considered equation.
