The generalized spectrum is computed via analytic continuations of the resolvent operators using a dense locally convex subspace $X$ of $\\mathcal{H}$ and its dual space $X'$. The three topological spaces $X \\subset \\mathcal{H} \\subset X'$ is called the rigged Hilbert space or the Gelfand triplet. In this paper, the generalized spectra of the Perron-Frobenius operators of the one-sided and two-sided shifts of finite types (symbolic dynamical systems) are determined. A one-sided subshift of finite type which is conjugate to the multiplication with the golden ration on $[0,1]$ modulo $1$ is also considered. A new construction of the Gelfand triplet for the generalized spectrum of symbolic dynamical systems is proposed by means of an algebraic procedure. The asymptotic formula of the iteration of Perron-Frobenius operators is also given. The iteration converges to the mixing state whose rate of convergence is determined by the generalized spectrum.", "revisions": [ { "version": "v1", "updated": "2021-06-22T22:34:01.000Z" } ], "analyses": { "keywords": [ "symbolic dynamical systems", "perron-frobenius operators", "generalized eigenvalues", "generalized spectrum", "hilbert space" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
