CONGEST lower bounds : beyond two-party reductions Oshman, Rotem
Description
Most CONGEST lower bounds are proven by reduction from two-party communication complexity. In this tutorial/talk we will discuss some limitations of existing reductions, and ways in which they might potentially be overcome. In particular, we'll cover:
- The two-party pointer-chasing lower bound of Nisan-Widgerson
- A connection between the broadcast congested clique and number-on-forehead communication complexity
- The basics of multi-party number-in - hand communication complexity.
