WebOct 2, 2024 · Various Alexandrov-Fenchel type inequalities have appeared and played important roles in convex geometry, matrix theory and complex algebraic geometry. It has been noticed for some time that they share some striking analogies and have intimate relationships. The purpose of this article is to shed new light on this by comparatively … Websame shape. It follows from the Legendre-Fenchel inequality, a family of non-metric distances BF,F∗(x,y) = F(x) + F∗(y) − xTy≥ 0 ∀x∈ X,y∈ Y that plays the role of canonical divergences of flat spaces in information geometry. Properties of the Legendre transformation are finally briefly listed.
