 XSMRI-GeoFlows/4/">Translating flows by sub-affine-critical powers of Gaus
 s curvature</a>\nby Kyeoungsu Choi as part of MATRIX-SMRI Symposium: Singu
 larities in Geometric Flows: An Ancient Perspective\n\n\nAbstract\nThe Gau
 ss curvature flow with sub-affine-critical powers generically develops Typ
 e II singularities\, while the flow with super-affine-critical powers conv
 erges to the round point. Therefore\, to analyze the singularities with sm
 all powers\, one needs to the translators as the model case of the limit a
 ncient flows. In this talk\, we show that blow-downs of translators are th
 e graphs of homogeneous functions such that the level sets of the graphs a
 re the shrinkers of the alpha-curve shortening flows. Then\, we discuss ho
 w to classify the translators by using the Morse index and Jacobi fields o
 f the shrinkers.\n

 olutions that have existed for all times in the past\, are of interest in 
 the study of geometric flows as they model singularities of the flows. In 
 this talk we will present some recent developments concerning convex ancie
 nt solutions. The main focus will be discussing a new way of constructing 
 and classifying collapsed solutions\, which\, for instance\, can be used t
 o provide new examples of eternal\, non translating\, convex solutions. Mo
 reover\, we will present a characterization of entire and non-entire conve
 x ancient solutions and furthermore provide a new classification result fo
 r ancient solutions of curve shortening flow with free boundary on a circl
 e. This is joint work with Mat Langford\, Stephen Lynch and Giuseppe Tinag

  3d round bowl\, or belongs to the one-parameter family of 3d oval bowls c
 onstructed by Hoffman-Ilmanen-Martin-White. This is joint work with Choi a

 th bounded index</a>\nby Nick Edelen as part of MATRIX-SMRI Symposium: Sin
 gularities in Geometric Flows: An Ancient Perspective\n\n\nAbstract\nA 7D 
 minimal and locally-stable hypersurface will in general have a discrete si
 ngular set\, provided it has no singularities modeled on a union of half-p
 lanes.  We show in this talk that the geometry/topology/singular set of th
 ese surfaces has uniform control\, in the following sense: if $M_i$ is a s
 equence of 7D minimal hypersurfaces with uniformly bounded index and area\
 , and discrete singular set\, then up to a subsequence all the $M_i$ are b
 i-Lipschitz equivalent\, and uniform Lipschitz bounds on the maps.  As a c
 onsequence\, we prove the space of $C^2$ embedded minimal hypersurfaces in
  a fixed $8$-manifold\, having index $\\leq I$\, area $\\leq \\Lambda$\, a
 nd discrete singular set\, divides into finitely-many diffeomorphism types

  The Nguyen as part of MATRIX-SMRI Symposium: Singularities in Geometric F
 lows: An Ancient Perspective\n\n\nAbstract\nIn this paper we prove an anal
 ogue of the Brakke's $\\e$-regularity theorem for the parabolic Allen--Cah
 n equation. In particular\, we show uniform $C^{2\,\\alpha}$ regularity fo
 r the transition layers converging to smooth mean curvature flows as $\\e\
 \rightarrow 0$. A corresponding gap theorem for entire eternal solutions o
 f the parabolic Allen--Cahn is also obtained. As an application of the reg
 ularity theorem\, we give an affirmative answer to a question of Ilmanen t
 hat there is no cancellation in BV convergence in the mean convex setting.
