Fifth-order b-family Novikov (FObFN) model with pseudo-peakons and multi-peakons.

In this paper, we discuss a fifth-order b -family peakon model with cubic nonlinearity, called the fifth-order b -family Novikov (FObFN) model. Interesting solutions are provided including explicit single pseudo-peakons, two-peakons, and N -peakon solutions. In particular, detailed dynamical interactions of two-peakons and three-peakons are investigated numerically. [ABSTRACT FROM AUTHOR]
