On steady motions of an ideal fibre-reinforced fluid in a curved stratum. Geometry and integrability
Dmitry K. Demskoi, Wolfgang K. Schief
It is shown that the kinematic equations governing steady motions of an ideal fibre-reinforced fluid in a curved stratum may be expressed entirely in terms of the intrinsic Gauss e…

The Lattice Sine-Gordon Equation as a Superposition Formula for an NLS-Type System
Dmitry K. Demskoi
We treat the lattice sine-Gordon equation and two of its generalised symmetries as a compatible system. Elimination of shifts from the two symmetries of the lattice sine-Gordon equ…
