This paper presents lower bounds on the time- and space-complexity of implementations that use the k compare-and-swap (k-CAS) synchronization primitives. We prove that the use of ...
We establish the first polynomial-strength time-space lower bounds for problems in the lineartime hierarchy on randomized machines with two-sided error. We show that for any inte...
We provide new and tight lower bounds on the ability of players to implement equilibria using cheap talk, that is, just allowing communication among the players. One of our main r...
We give the first time-space tradeoff lower bounds for Resolution proofs that apply to superlinear space. In particular, we show that there are formulas of size N that have Reso...
We consider wait-free implementations of a regular read/ write register for unauthenticated data using a collection of 3t + k base objects, t of which can be subject to Byzantine ...
