Yp. Jiang, A proof of the existence and simplicity of a maximal eigenvalue for Ruelle-Perron-Frobenius operators, LETT MATH P, 48(3), 1999, pp. 211-219
We give a new proof of a result due to Ruelle about the existence and simpl
icity of a unique maximal eigenvalue for a Ruelle-Perron-Frobenius operator
acting on some Holder continuous function space.
