A deductive approach to the solution of the problem of optimal pairs trading from the viewpoint of stochastic control with timedependent parameters
Charalambous, Kyriakos; Sophocleous, Christodoulos; O'Hara, John G.; Leach, Peter G. L. (2015)In a fairly recent paper (2008 American Control Conference, June 1113, 10351039), the problem of dealing with trading in optimal pairs was treated from the viewpoint of stochastic control. The analysis of the subsequent ...

Lie Symmetries for Variable Coefficient Compound KdVBurgers Equations
Charalambous, Kyriakos; Sophocleous, Christodoulos (2019)

Article
Lie symmetries of a system arising in plasma physics
Charalambous, Kyriakos; Sophocleous, Christodoulos (2018)Lie group classification for a diffusiontype system that has applications in plasma physics is derived. The classification depends on the values of 5 parameters that appear in the system. Similarity reductions are presented. ...

Lie Symmetry Analysis of a ThirdOrder Equation Arising from a General Class of Lotka–Volterra Chains
Charalambous, Kyriakos; Sophocleous, Christodoulos (Springer, 2018)In the literature has recently appeared a class of bicubic equations from the study of a general class of Lotka–Volterra chains. Lie symmetry analysis is performed for this nonlinear partial differential equation and a ...

Mindfulness, impulsivity, and moral disengagement as parameters of bullying and victimization at school
Georgiou, Stelios N.; Charalambous, Kyriakos; Stavrinides, Panayotis (2020)

Article
On a sequence of higherorder nonlinear diffusionconvection equations
Charalambous, Kyriakos; Sophocleous, Christodoulos (2019)Motivated by the existence of the thin film equations, fourth and sixth order, which are generalizations of the diffusion equation, we consider a sequence of higher order nonlinear diffusionconvection equations. We ...

Article
Symmetry analysis for a class of nonlinear dispersive equations
Charalambous, Kyriakos; Sophocleous, Christodoulos (2015)A class of dispersive equations is studied within the framework of group analysis of differential equations. The enhanced Lie group classification is achieved. The complete list of equivalence transformations is presented. ...

Article
Symmetry and singularity analyses of some equations of the fifth and sixth order in the spatial variable arising from the modelling of thin films
Charalambous, Kyriakos; Sophocleous, Christodoulos; Leach, Peter G. L. (2013)In the modelling of the flow of thin films higherorder derivatives in the spatial variable are introduced to model nonlinear effects. We examine nonlinear evolution equations of the fifth and sixth orders in the spatial ...

Article
Symmetry properties for a generalised thin film equation
Charalambous, Kyriakos; Sophocleous, Christodoulos (2013)Symmetry properties are presented for a fourthorder parabolic equation written in conservation form. It was introduced in the literature as a generalisation of the fourthorder thin film equation. We derive equivalence ...
