Open AccessFrom one to infinity: symmetries of integrable systems
Integrable systems constitute an essential part of modern physics. Traditionally, to approve a model is integrable one has to find its infinitely many symmetries or conserved quantities. In this letter, taking...

Open AccessDeformation conjecture: deforming lower dimensional integrable systems to higher dimensional ones by using conservation laws
Utilizing some conservation laws of (1+1)-dimensional integrable local evolution systems, it is conjectured that higher dimensional integrable equations may be regularly constructed by a deformation algorithm....

Open AccessDuality of positive and negative integrable hierarchies via relativistically invariant fields
It is shown that the relativistic invariance plays a key role in the study of integrable systems. Using the relativistically invariant sine-Gordon equation, the Tzitzeica equation, the Toda fields and the seco...

Coherent structure of Alice–Bob modified Korteweg de-Vries equation
To describe two-place events, Alice–Bob systems have been established by means of the shifted parity and delayed time reversal in the preprint ar**v:1603.03975v2

Open AccessAlice-Bob Physics: Coherent Solutions of Nonlocal KdV Systems
In natural and social science, many events happened at different space-times may be closely correlated. Two events, A (Alice) and B (Bob) are defined correlated if one event is determined by another, say, ...

Open AccessPrimary Branch Solutions of First Order Autonomous Scalar Partial Differential Equations via Lie Symmetry Approach
A primary branch solution (PBS) is defined as a solution with m independent n − 1 dimensional arbitrary functions for an m order n dimensional partial differential equation (PDE). PBSs of arbitrary first order sc...

Bosonization, singularity analysis, nonlocal symmetry reductions and exact solutions of supersymmetric KdV equation
Assuming that there exist at least two fermionic parameters, the classical \( \mathcal{N}=1 \) supersymmetric Korteweg-...

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...
