Abstract

We consider scalar Liénard equations

¨x(t) = f (x(t))˙x(t)+ g(x(t)), x(t) 2R(1)

and the diffeomorphisms ' : R2!R2 in the form

phi(x, t) = (beta(x), a.t +apha(x))(2)

where the derivative of the function is non zero and where the real number a is non zero. The aim

result of this paper is to study the symmetries in the form given by (2) for the equation (1).
