DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/8/">On 
 the regularity of Ricci flows coming out of metric spaces.</a>\nby Miles S
 imon (University Magdeburg) as part of Online Seminar "Geometric Analysis"
 \n\n\nAbstract\nJoint work with Alix Deruelle\, Felix Schulze\n\nWe consid
 er solutions to Ricci flow defined on manifolds M for a time interval $(0\
 ,T)$ whose Ricci curvature is bounded uniformly in time from below\, and f
 or which the norm of the  full curvature tensor at time $t$  is bounded by
  $c/t$ for some fixed constant $c>1$ for all $t \\in (0\,T)$.\nFrom previo
 us works\, it is known that if the solution is complete for all times $t>0
 $\, then there is a limit\nmetric space $(M\,d_0)$\, as time t approaches 
 zero. We show : if there is a open region $V$ on which $(V\,d_0)$ is *smoo
 th*\, then the\nsolution can be extended smoothly to time zero on $V$.\n
