Poisson-Delaunay approximation
For a Borel set $A$ and a stationary Poisson point process $\eta_t$ in $\mathbb R^d$ of intensity $t>0$, the Poisson-Delaunay approximation $ A_{\eta_t}$ of $A$ is the union of all Delaunay cells generated by $\eta_t$ with center in $A$. It is shown that $\lambda_d(A_{\eta_t})$ is an unbiased estimator for $\lambda_d(A)$, variance bounds and a quantitative central limit theorem are given. The asymptotic behaviour of the symmetric difference $\lambda_d(A\Delta A_{\eta_t})$ is derived as $t \to\infty$.
