We consider a certain class of linear maps $L : X \\to X$ (called weighted shift operators). We fix a suitable {\\it a priori} probability measure $m$ on the kernel of $L$ in order to introduce the Ruelle operator $\\mathcal{L}_A$ associated to a bounded H\\\"older continuous potential $A: X \\to \\mathbb{R}$. We adapt the Thermodynamic Formalism for generalized $XY$ models (in the case the alphabet is non-compact) to the present setting. We are able to show the existence of eigenvalues, eigenfunctions and eigenprobabilities for $\\mathcal{L}_A$. Moreover, we show the existence of $L$-invariant ergodic probabilities with full support in a similar manner as in Classical Thermodynamic Formalism. Finally, these results are extended to a large class of linear operators defined on Banach spaces.", "revisions": [ { "version": "v1", "updated": "2019-10-10T22:54:45.000Z" } ], "analyses": { "subjects": [ "37D35" ], "keywords": [ "discrete time linear dynamics", "invariant probabilities", "probability", "real vector space", "invariant ergodic probabilities" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
