SUMMARY:Jona Röhrig (HU Berlin) - 
DESCRIPTION:Speaker: Jona Röhrig\n\nTitle: Gromov compactness in Lorentzia
 n Length Spaces\n\nAbstract:\nSince it was started in 2018 by Kunzinger an
 d Sämann\, the topic of Lorentzian length spaces has grown in popularity.
  Its goal is to study geometry on certain types of Lorentzian metric space
 s\, lowering the regularity conditions necessary for General Relativity as
  much as possible. This is done by adapting the ideas of metric geometry t
 o the Lorentzian setting. This allows\, for example\, the definition of se
 ctional curvature or some rungs of the causal ladder in a synthetic versio
 n\, as well as the Hausdorff dimension.\nAdditionally\, the notion of Grom
 ov-Hausdorff distance can be transferred to the Lorentzian setting\, raisi
 ng the question of whether\, and to what extent\, the curvature-driven Gro
 mov compactness theorem holds valid.\nIn my talk\, I want to give a brief 
 introduction to the general topic and then shed some light on the last que
 stion.
