文摘
- •
We study the dynamics of solitary waves in the perturbed granular scalar model.
- •
We devise a special analytical procedure depicting the modulation of solitary waves.
- •
We report the formation of a special type of stationary primary pulses.
- •
Stationary pulses are attractors which are formed through a saddle–node bifurcation.
