On the "Second Yamabe Invariant" by B.Ammann and E.Humbert.


This is a report of a reading I did last semester. In this paper, the authors defined the second Yamabe invariant, and showed that the second Yamabe invariant could not be attained for connected spaces. They define a more generalized form of metrics and showed that under suitable assumptions on the first and second Yamabe invariant, the second Yamabe invariant can be obtained by a generalized metric.
