Let be a semi-hyperbolic polynomial in the sense of Carleson-Jones-Yoccoz with an attracting point. The goal of this paper is to show that one can define a semi-hyperbolic deformation such that the attracting cycle becomes parabolic for the limit polynomial and that and are semi-conjugate. This deformation is defined by pinching curves in appropriate quotient spaces.
