Title: 
Unfriendly colorings of measurepreserving graphs of finite cost

Abstract: 
We show that any measurepreserving Borel graph on a standard probability space with finite average degree admits a Borel unfriendly coloring on a conull set. This generalizes the results for group actions discussed last semester, and is joint work with Omer Tamuz.
