# Basic Notions: Benjamin Weiss (HUJI) "Groups with property T have and "cost" of equivalence relations"

4:00pm to 5:15pm

The cost of a measure-preserving equivalence relation is a quantitative measure of its complexity. I will

explain what the cost is and then discuss a recent result of Tom Hutchcroft and Gabor Pete in which they construct,

for any group with property T, a free ergodic measure preserving action with cost 1.
