Infinitesimal Thurston Rigidity and the Fatou-Shishikura Inequality
Abstract: We prove a refinement of the Fatou-Shishikura Inequality - that the total count of nonrepelling cycles of a rational map is
less than or equal to the number of independent infinite
forward critical orbits - from a suitable application of
Thurston's Rigidity Theorem - the injectivity of $I-f_*$ on
spaces of meromorphic quadratic differentials.
