In this work we present results on the construction of λ-symmetries for ordinary differential equation using ideas derived from the notion of nonlocal symmetries and Jacobi last multiplier. We then apply the results obtained to the case of ordinary difference equations.

Abstract
In this work we present results on the construction of λ-symmetries for ordinary differential equation using ideas derived from the notion of nonlocal symmetries and Jacobi last multiplier. We then apply the results obtained to the case of ordinary difference equations.File in questo prodotto:
