Lower bounds for number-in-hand multiparty communication complexity, made easy
In this paper we prove lower bounds on randomized multiparty communication complexity, both in the blackboard model (where each message is written on a blackboard for all players ...

A Separation of NP and coNP in Multiparty Communication Complexity
: We prove that coNP MA in the number-on-forehead model of multiparty communication complexity for up to k = (1 - )logn players, where > 0 is any constant. Specifically, we con...

Hadamard Tensors and Lower Bounds on Multiparty Communication Complexity
We develop a new method for estimating the discrepancy of tensors associated with multiparty communication problems in the “Number on the Forehead” model of Chandra, Furst and...
