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.
