In this article, we prove that the ⟨p,q⟩ condition holds, first by using Fuchs index of complex Kawahara equation, and then proving all meromorphic solutions equations belong to class W. Moreover, method is employed get equation traveling wave exact equation. Our results reveal rational ur(x+νt) simply periodic us,1(x+νt) are solitary solutions, while us,2(x+νt) not real-valued. Finally, comput...
