A group theory approach towards some rational difference equations
M. Folly-Gbetoula, N. Mnguni, AH Kara
A full Lie point symmetry analysis of rational difference equations is performed. Non-trivial symmetries are derived and exact solutions using these symmetries are obtained.

Symmetry, reductions and exact solutions of systems of difference equations
JJ Bashingwa, AH Kara, M Folly-Gbetoula
We apply symmetry and invariance methods to analyse systems of difference equations. Non trivial symmetries are derived and their exact solutions obtained.
