Abstract

Let SS be a closed oriented surface of genus at least two. Gallo, Kapovich, and Marden asked if 2\pi-graftings produce all projective structures on SS with arbitrarily fixed holonomy (Grafting Conjecture). In this paper, we show that the conjecture holds true "locally" in the space GLGL of geodesic laminations on SS via a natural projection of projective structures on SS into GLGL in the Thurston coordinates. In the sequel paper, using this local solution, we prove the conjecture for generic holonomy.
