Cardy's formula for critical Poisson-Voronoi percolation (annealed crossing part of Schramm's Problem 2.12)

Theorem 1.1: for every bounded Jordan domain with four marked boundary points, the annealed probability of a black crossing in critical Poisson-Voronoi percolation converges to Cardy's function F(x)F(x) of the conformal cross-ratio xx. A corollary gives a quenched L2L^2 limit for fixed rectangles. The companions prove that the expected number of pivotal cells for a unit-square crossing is asymptotic to c ε−3/4c\,\varepsilon^{-3/4} and that conditional near-critical crossing-threshold laws for rational polygonal quads converge in probability over tessellations to the triangular-lattice law. Not shown: convergence of interfaces to SLE(6) or the full conformal invariance of Schramm's problem.
