Abstract:	In this paper we study the double transpose of the L1(X, B(X), ν)-extensions of the Ruelle transfer operator L f associated to a general real continuous potential f ∈ C(X), where X = EN, the alphabet E is any compact metric space and ν is a maximal eigenmeasure. For this operator, denoted by L∗∗ f , we prove the existence of some non negative eigenfunction, in the Banach lattice sense, associated to ρ(L f ), the spectral radius of the Ruelle operator acting on C(X). As an application, we obtain a sufficient condition ensuring that the extension of the Ruelle operator to L1(X, B(X), ν) has an eigenfunction associated to ρ(L f ). These eigenfunctions agree with the usual maximal eigenfunctions, when the potential f belongs to the Hölder,Walters or Bowen class. We also construct solutions to the classical and generalized variational problem, using the eigenvector constructed here.
