For this extension, we prove the existence of non-negative eigenfunctions, in the Banach lattice sense, associated to $\\lambda_{f}$, the spectral radius of the Ruelle operator acting on $C(\\Omega)$. As an application, we show that the natural extension of the Ruelle operator to $L^1(\\Omega,\\mathscr{B}(\\Omega),\\nu)$ (for a suitable Borel probability measure $\\nu$) always has an eigenfunction associated to $\\lambda_{f}$. These eigenfunctions agree with the usual maximal eigenfunctions, when the potential $f$ is either in H\\\"older or Walters spaces. We also constructed solutions to the classical (finite-state spaces) and generalized (general compact metric spaces) variational problem avoiding the standard normalization technique.", "revisions": [ { "version": "v1", "updated": "2017-10-10T22:29:12.000Z" } ], "analyses": { "subjects": [ "28Dxx", "37D35" ], "keywords": [ "ruelle operator", "double transpose", "general compact metric spaces", "banach lattice sense", "general real continuous potential" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable" } } }
