Approximate centerpoints with proofs
We present the IteratedTverberg algorithm, the first deterministic algorithm for computing an approximate centerpoint of a set S Rd with running time subexponential in d. The alg...

Separating Complexity Classes Using Structural Properties
We study the robustness of complete sets for various complexity classes. A complete set A is robust if for any f(n)-dense set S ∈ P, A−S is still complete, where f(n) ranges f...

Global Conformal Parameterization
We solve the problem of computing global conformal parameterizations for surfaces with nontrivial topologies. The parameterization is global in the sense that it preserves the con...
