Modulational instability of small amplitude periodic traveling waves in the -family of Novikov equation
Xin Zhao, Lin Lu, Aiyong Chen
We study the modulational instability of smooth, small-amplitude periodic traveling wave solutions to the -family of Novikov equation with cubic nonlinearity with an arbitrary c…
