Abstract

It is well-known that the geometric pressure function (formula presented.) of the Chebyshev quadratic map T₂(x) = 1 - 2 x²(x∈ R) is not differentiable at t= - 1. We show that this phase transition can be “removed”, by an arbitrarily small singular perturbation of the map T₂ into Hénon-like diffeomorphisms. A proof of this result relies on an elaboration of the well-known inducing techniques adapted to Hénon-like dynamics near the first bifurcation.
