Deformations of noncompact projective manifolds

Samuel A Ballas

Algebraic & Geometric Topology 14 (2014) 2595–2625
Abstract

In this paper, we demonstrate that the complete hyperbolic structures of various two-bridge knots and links cannot be deformed to inequivalent strictly convex projective structures. We also prove a complementary result showing that under certain rigidity hypotheses, branched covers of amphicheiral knots admit nontrivial, strictly convex deformations near their complete hyperbolic structure.

Keywords
projective structures, two-bridge knots, rigidity
