摘要：Barreira and Valls proved in [J. Dyn. Diff. Equ., 22 (2010): 787-803] the C^1 dependence of C^0 linearization on parameters for nonuniformly hyperbolic diffeomorphisms, whose nonlinear parts depend on the parameters but linear parts do not. In this talk, we allow the linear parts to depend on the parameters, where only Holder dependence is possible and a difficulty arises: the projections in the nonuniform exponential dichotomy do not have explicit expressions. We will overcome the difficulty by giving a new result on the Holder dependence of nonuniform exponential dichotomy and constructing the conjugacy in a different way.
