Optimizing n-variate (n+k)-nomials for small k
We give a high precision polynomial-time approximation scheme for the supremum of any honest n-variate (n + 2)-nomial with a constant term, allowing real exponents as well as real...

Private Information Retrieval Based on the Subgroup Membership Problem
Abstract. Many algorithmic problems, which are used to prove the security of a cryptographic system, are shown to be characterized as the subgroup membership problem. We then apply...

Equivelar maps on the torus
Abstract. We give a classification of all equivelar polyhedral maps on the torus. In particular, we classify all triangulations and quadrangulations of the torus admitting a vertex...

Invariant games
In the context of 2-player removal games, we define the notion of invariant game for which each allowed move is independent of the position it is played from. We present a family ...

Sign Modules in Secure Arithmetic Circuits
In this paper, we study the complexity of secure multiparty computation using only the secure arithmetic black-box of a finite field, counting the cost by the number of secure m...
