Weierstrass elliptic solutions to a Zakharov equation in plasmas with power law nonlinearity
In this paper, travelling wave solutions for the Zakharov equation in plasmas with power law nonlinearity are studied by using the Weierstrass elliptic function method. As a result, some previously known solutions are recovered, and at the same time some new ones are also given.
