A note on enhanced (G0/G)-expansion method in nonlinear physics

(in lingua inglese)

In this paper, an enhanced (G0/G)-expansion method has been successfully applied to find the solitary wave solutions for the (2 + 1)-dimensional Zoomeron equation. The method has been used to find new exact solutions. As a result, hyperbolic function solutions, and trigonometric function solutions with several free parameters have been obtained. The obtained solutions with free parameters may be important to explain physical phenomena.
