Positive Lyapunov exponent of discrete analytic Jacobi operator. <i>Electronic Journal of Differential Equations, 2017</i>(39), pp. 1-12.1072-6691https://hdl.handle.net/10877/15563In this article, we study the Lyapunov exponent of discrete analytic Jacobi operator with a family of some mappings on the torus. By applying the theory of subharmonic functions, we prove that the Lyapunov exponent is positive, if the coupling number is large.Text12 pages1 file (.pdf)enAttribution 4.0 InternationalPositive Lyapunov exponentJacobi operatorSubharmonic functionArticle
