## Bifurcations of travelling wave solutions for the $$K(n,-n,2n)$$ equations.(English)Zbl 1157.37021

For the following $$K(n,-n,2n)$$ equations $$u_t=a(u'')_x+b[u^{-n}(u^{2n})_{xx}]_{x}=0$$ where $$a,b$$ are two nonzero real numbers, $$n$$ is positive integer. A. M. Wazwaz [Appl. Math. Comput., 173, No. 1, 213–230 (2006; Zbl 1089.65113)] has considered some compact and non-compact solutions of travelling wave structure. The authors investigate bifurcations of travelling wave solutions in the five-parameter space $$(a, b, c, g, n)$$ and prove the existence of solitary wave solutions, solitary cusp wave, kink and anti-kink wave solutions and uncountably infinite many smooth and non-smooth periodic wave solutions.
