Doubly periodic patterns of modulated hydrodynamic waves: Exact solutions of the Davey-Stewartson system
Exact doubly periodic standing wave patterns of the Davey-Stewartson (DS) equations are derived in terms of rational expressions of elliptic functions. In fluid mechanics, DS equations govern the evolution of ...

Nonlinear excitations and “peakons” of a (2+1)-dimensional generalized Broer-Kaup system
Shallow water waves and a host of long wave phenomena are commonly investigated by various models of nonlinear evolution equations. Examples include the Korteweg–de Vries, the Camassa–Holm, and the Whitham–Bro...
