A Different Look at Massive GravityQMAP Seminar
|Speaker: ||Eric Bergshoeff, Groningen|

We discuss and review two different ways of giving mass to the graviton in three
dimensions: by adding higher derivative terms to
the Einstein action or by adding an explicit (non-linear) mass term.
We focus in particular on the issue of whether and how these models can be made supersymmetric.
We finally briefly discuss how both models can be viewed
as (different) truncations of a bi-metric model of gravity.
