On the fourier tails of bounded functions over the discrete cube
In this paper we consider bounded real-valued functions over the discrete cube, f : {-1, 1}n [-1, 1]. Such functions arise naturally in theoretical computer science, combinatorics...

Almost random graphs with simple hash functions
We describe a simple randomized construction for generating pairs of hash functions h1, h2 from a universe U to ranges V = [m] = {0, 1, . . . , m - 1} and W = [m] so that for ever...

Automating the Detection of Snapshot Isolation Anomalies
Snapshot isolation (SI) provides significantly improved concurrency over 2PL, allowing reads to be non-blocking. Unfortunately, it can also lead to non-serializable executions in ...
