Bounds on the Fourier Coefficients of the Weighted Sum Function
We estimate Fourier coefficients of a Boolean function which has recently been introduced in the study of read-once branching programs. Our bound implies that this function has an...

Optimal clearing algorithms for multi-unit single-item and multi-unit combinatorial auctions with demand/supply function bidding
This paper presents new clearing algorithms for multi-unit single-item and multi-unit combinatorial auctions with piecewise linear demand/supply functions. We analyse the complexi...

Constant-Round Non-malleable Commitments from Sub-exponential One-Way Functions
We present a constant-round non-malleable commitment scheme based on the existence of sub-exponential one-way functions and using a blackbox proof of security. As far as we know, t...
