Entropy rigidity for finite volume strictly convex projective manifolds

We prove entropy rigidity for finite volume strictly convex projective manifolds in dimensions $\ge 3$, generalizing the work of arXiv:1708.03983 to the finite volume setting. The rigidity theorem uses the techniques of Besson, Courtois, and Gallot’s entropy rigidity theorem. It implies uniform lower bounds on the volume of any finite volume strictly convex projective manifold in dimensions $\ge 3$.
