2-Source Extractors under Computational Assumptions and Cryptography with Defective Randomness
Abstract— We show how to efficiently extract truly random bits from two independent sources of linear min-entropy, under a computational assumption. The assumption we rely on is...

Linear Systems over Composite Moduli
We study solution sets to systems of generalized linear equations of the form ℓi(x1, x2, · · · , xn) ∈ Ai (mod m) where ℓ1, . . . , ℓt are linear forms in n Boolean var...

Symmetry and Approximability of Submodular Maximization Problems
Abstract— A number of recent results on optimization problems involving submodular functions have made use of the ”multilinear relaxation” of the problem [3], [8], [24], [14]...

Convergence of Local Dynamics to Balanced Outcomes in Exchange Networks
— Bargaining games on exchange networks have been studied by both economists and sociologists. A Balanced Outcome [9], [15] for such a game is an equilibrium concept that combine...
