Conservation laws for a class of nonlinear equations with variable coefficients on discrete and noncommutative spaces
M. Klimek
The conservation laws for a class of nonlinear equations with variable coefficients on discrete and noncommutative spaces are derived. For discrete models the conserved charges are…

kappa-deformed realisation of D=4 conformal algebra
Malgorzata Klimek, Jerzy Lukierski
We describe the generators of kappa-conformal transformations, leaving invariant the kappa-deformed d'Alembert equation. In such a way one obtains the conformal extension of the of…
