Conditional hardness for satisfiable 3-CSPs
In this paper we study a fundamental open problem in the area of probabilistic checkable proofs: What is the smallest s such that NP naPCP1,s[O(log n), 3]? In the language of har...

Fast Evaluation of Union-Intersection Expressions
Abstract. We show how to represent sets in a linear space data structure such that expressions involving unions and intersections of sets can be computed in a worst-case efficient ...

Analysis of Degrees of Freedom of Interfering MISO Broadcast Channels
— In this paper, we provide a lower and upper bound for the number of degrees of freedom (DOF) of B multipleinput single-output (MISO) broadcast channels (BC) where each base sta...
