We study the communication complexity of linear algebraic problems over finite fields in the multi-player message passing model, proving a number of tight lower bounds. We give a general framework for reducing these multi-player problems to their two-player counterparts, showing that the randomized s-player communication complexity of these problems is at least s times the randomized two-player communication complexity. Provided the problem has a certain amount of algebraic symmetry, we can…

• Computer Science, Mathematics
SIAM J. Comput.
• 2016
This paper proves lower bounds on randomized multiparty communication complexity, both in the blackboard model and in the message-passing model, and introduces a new technique for proving such bounds, called symmetrization, which is natural, intuitive, and often easy to use.

### Distributed Estimation of Generalized Matrix Rank: Efficient Algorithms and Lower Bounds

• Computer Science, Mathematics

This work shows that any deterministic algorithm solving the generalized matrix rank estimation problem must communicate Ω(n2) bits, which is order equivalent to transmitting the whole matrix, and proposes a randomized algorithm that communicates only e O(n) bits.

### A Rounds vs. Communication Tradeoff for Multi-Party Set Disjointness

• Computer Science
2017 IEEE 58th Annual Symposium on Foundations of Computer Science (FOCS)
• 2017
The trade-off between the number of interaction rounds the authors allow the players, and the total number of bits they must send to solve set disjointness is studied, and it is shown that if R rounds of interaction are allowed, the communication cost is &#x03A9;(nk^{1/R}/R^4), which is nearly tight.

• Computer Science

• 2015
It is shown that for a large class of natural functions like Set-Disjointness the communication cost is essentially n times the cost of the optimal Steiner tree connecting the terminals, and for natural composed functions like Element-Distinctness ED and XOR the naive protocols suggested by their definition is optimal for general networks.

An entirely different proof of Razborov's result is given, using the original, one-dimensional discrepancy method, which refutes the commonly held intuition that the original discrepancy method fails for functions such as DISJOINTNESS and establishes a large new class of total Boolean functions whose quantum communication complexity is at best polynomially smaller than their classical complexity.
