内容介绍:Characterizations of Legendre transforms via the concept of duality were established by Artstein-Avidan and Milman [Ann. of Math. 2009]. One of the key points in their study is that dualities are “strong” valuations, namely, the “maximum” and the “minimum” of functions are interchanged. In this talk, I will present some new characterizations of Legendre transforms in the affine theory of valuations.
