DESCRIPTION:Title: Valuative invariants for spherical varieties and applica
 tions to K-stability\n\nAbstract: The Yau-Tian-Donaldson conjecture aims t
 o establish a connection between the existence of canonical metrics\, such
  as Kähler-Einstein metrics and constant scalar curvature Kähler metrics\,
  and stability conditions in algebraic geometry. In this talk\, we will di
 scuss the alpha invariant and the delta invariant\, two crucial valuative 
 invariants relevant to the Yau-Tian-Donaldson conjecture. We will provide 
 formulas of these invariants for ample line bundles on spherical varieties
 \, a class of varieties known for their large symmetry. Subsequently\, we 
 will explore applications of these formulas\n\nto K(Ding-)stability proble
