Symmetries and reductions of integrable nonlocal partial differential equations [PDF]

open access: yesSymmetry, 2019
In this paper, symmetry analysis is extended to study nonlocal differential equations, in particular two integrable nonlocal equations, the nonlocal nonlinear Schr\"odinger equation and the nonlocal modified Korteweg--de Vries equation.

Spike solutions to a nonlocal differential equation

open access: yesCommunications on Pure & Applied Analysis, 2005
In this paper we consider a nonlocal differential equation, which is a limiting equation of one dimensional Gierer-Meinhardt model. We study the existence of spike steady states and their stability. We also construct a single-spike quasi-equilibrium solution and investigate the dynamics of spike-like solutions.

Symmetry and Intertwining Operators for the Nonlocal Gross-Pitaevskii Equation [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
We consider the symmetry properties of an integro-differential multidimensional Gross-Pitaevskii equation with a nonlocal nonlinear (cubic) term in the context of symmetry analysis using the formalism of semiclassical asymptotics.

Nonlocal Symmetries for Time-Dependent Order Differential Equations [PDF]

open access: goldSymmetry, 2018
A new type of ordinary differential equation is introduced and discussed, namely, the time-dependent order ordinary differential equations. These equations can be solved via fractional calculus and are mapped into Volterra integral equations of second kind with singular integrable kernel. The solutions of the time-dependent order differential equations
