Paper Summary

The measurable cohomology class of a linear holonomy cocycle of a foliation can provide information about the characteristic classes of the foliation. When combined with previous research, this can lead to vanishing theorems for characteristic classes of certain actions of lattices in higher rank semisimple Lie groups.
