DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/88/">
 4-dimensional specific aspects of Ricci flows</a>\nby Tristan Ozuch (MIT) 
 as part of CRM - Séminaire du CIRGET / Géométrie et Topologie\n\nLectur
 e held in PK-5115.\n\nAbstract\nRicci flow has been extensively studied\, 
 and most results are either true only in dimension 3 or hold in every dime
 nsion. However\, given the potential topological applications\, a theory s
 pecific to the 4-dimensional situation is desirable. In this discussion\, 
 I will present tools and techniques that are unique to the 4-dimensional c
 ase.\n\nTogether with A. Deruelle\, we introduce a notion of stability for
  orbifold singularities. This notion helps to explain the formation of orb
 ifold singularities along Ricci flow. Moreover\, in collaboration with K. 
 Naff\, we utilize self-duality in dimension 4 to simplify the evolution eq
 uations of curvature. This approach lets us uncover intriguing connections
  between Ricci flow and Yang-Mills flow.\n
