 ture</a>\nby Kyeoungsu Choi as part of MATRIX-SMRI Symposium: Singularitie
 s in Geometric Flows: An Ancient Perspective\n\n\nAbstract\nThe Gauss curv
 ature flow with sub-affine-critical powers generically develops Type II si
 ngularities\, while the flow with super-affine-critical powers converges t
 o the round point. Therefore\, to analyze the singularities with small pow
 ers\, one needs to the translators as the model case of the limit ancient 
 flows. In this talk\, we show that blow-downs of translators are the graph
 s of homogeneous functions such that the level sets of the graphs are the 
 shrinkers of the alpha-curve shortening flows. Then\, we discuss how to cl
 assify the translators by using the Morse index and Jacobi fields of the s
 hrinkers.\n

  joint work in collaboration with Christoph Böhm in which we obtain struc

 etric action of a connected Lie group. As an application\, we prove the Al
 ekseevskii conjecture (1975): any connected homogeneous Einstein space of 
 negative scalar curvature is diffeomorphic to a Euclidean space.\n

  Ancient Perspective\n\n\nAbstract\nAncient solutions\, which are solution
 s that have existed for all times in the past\, are of interest in the stu
 dy of geometric flows as they model singularities of the flows. In this ta
 lk we will present some recent developments concerning convex ancient solu
 tions. The main focus will be discussing a new way of constructing and cla
 ssifying collapsed solutions\, which\, for instance\, can be used to provi
 de new examples of eternal\, non translating\, convex solutions. Moreover\
 , we will present a characterization of entire and non-entire convex ancie
 nt solutions and furthermore provide a new classification result for ancie
 nt solutions of curve shortening flow with free boundary on a circle. This
  is joint work with Mat Langford\, Stephen Lynch and Giuseppe Tinaglia.\n

 ded index</a>\nby Nick Edelen as part of MATRIX-SMRI Symposium: Singularit
 ies in Geometric Flows: An Ancient Perspective\n\n\nAbstract\nA 7D minimal
  and locally-stable hypersurface will in general have a discrete singular 
 set\, provided it has no singularities modeled on a union of half-planes. 
  We show in this talk that the geometry/topology/singular set of these sur
 faces has uniform control\, in the following sense: if $M_i$ is a sequence
  of 7D minimal hypersurfaces with uniformly bounded index and area\, and d
 iscrete singular set\, then up to a subsequence all the $M_i$ are bi-Lipsc
 hitz equivalent\, and uniform Lipschitz bounds on the maps.  As a conseque
 nce\, we prove the space of $C^2$ embedded minimal hypersurfaces in a fixe
 d $8$-manifold\, having index $\\leq I$\, area $\\leq \\Lambda$\, and disc
 rete singular set\, divides into finitely-many diffeomorphism types.\n

 uyen as part of MATRIX-SMRI Symposium: Singularities in Geometric Flows: A
 n Ancient Perspective\n\n\nAbstract\nIn this paper we prove an analogue of
  the Brakke's $\\e$-regularity theorem for the parabolic Allen--Cahn equat
 ion. In particular\, we show uniform $C^{2\,\\alpha}$ regularity for the t
 ransition layers converging to smooth mean curvature flows as $\\e\\righta
 rrow 0$. A corresponding gap theorem for entire eternal solutions of the p
 arabolic Allen--Cahn is also obtained. As an application of the regularity
  theorem\, we give an affirmative answer to a question of Ilmanen that the
 re is no cancellation in BV convergence in the mean convex setting.\n
