Byzantine disk paxos: optimal resilience with byzantine shared memory
We present Byzantine Disk Paxos, an asynchronous shared-memory consensus algorithm that uses a collection of n > 3t disks, t of which may fail by becoming non-responsive or arb...

Making Hard Problems Harder
We consider a general approach to the hoary problem of (im)proving circuit lower bounds. We define notions of hardness condensing and hardness extraction, in analogy to the corres...

Better extractors for better codes?
We present an explicit construction of codes that can be list decoded from a fraction (1 - ) of errors in sub-exponential time and which have rate / logO(1) (1/). This comes close...

LTL Path Checking Is Efficiently Parallelizable
We present an AC1 (logDCFL) algorithm for checking LTL formulas over finite paths, thus establishing that the problem can be efficiently parallelized. Our construction provides a f...
