	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.
