Soliton gas in bidirectional dispersive hydrodynamics
Soliton gas in bidirectional dispersive hydrodynamics
The theory of soliton gas had been previously developed for unidirectional integrable dispersive hydrodynamics in which the soliton gas properties are determined by the overtaking elastic pairwise interactions between solitons. In this paper, we extend this theory to soliton gases in bidirectional integrable Eulerian systems where both head-on and overtaking …
