The degeneration of convex ℝℙ^2 structures on surfaces

Zhang, Tengren

Abstract

Let M be a compact surface of negative Euler characteristic and let C(M) be the deformation space of convex real projective structures on M with positive hyperbolic holonomy. For every choice of pants decomposition for M, there is a well-known parameterization of C(M) known as the Goldman parameterization. In this paper, we study how some geometric properties of the real projective structure on M degenerate as we deform it so that the internal parameters of the Goldman parameterization leave every compact set, while the boundary invariants remain bounded away from zero and infinity.
