Title: Infimum of Calabi functionals and worst test-configurations on toric manifolds

Abstract:Donaldson has given a lower bound of Calabi functional by the infimum of Futaki invariant, and conjectures that they are should be equal. On toric manifolds, Szekelyhidi has proved this conjecture through Calabi’s flow. And in the un-stable case, the worst test-configuration gives a canonical semi-stable decomposition of the polytope. In this talk I will introduce this work and the related background of Kahler geometry and toric manifolds will also be given.
