SUMMARY:Jona Röhrig: Gromov compactness in Lorentzian length spaces - 
DESCRIPTION:Speaker: Jona Röhrig (HU Berlin)\n\nTitle: Gromov compactness
  in Lorentzian length spaces\n\nAbstract:\nIn this talk\, we discuss neces
 sary conditions for a timelike sectional curvature driven Gromov compactne
 ss theorem in the context of Lorentzian length spaces (LLS). We begin with
  an overview of length spaces as a generalization of Riemannian manifolds 
 and Lorentzian length spaces as generalizations of spacetimes\, alongside 
 the notion of synthetic sectional curvature bounds in these spaces. Next\,
  we examine how to adapt the Gromov-Hausdorff distance for the Lorentzian 
 context and explore the generalization of Gromov compactness theorems from
  the metric to the Lorentzian setting. For a potential curvature-driven co
 mpactness theorem in the Lorentzian case\, we propose an initial proof app
 roach and provide examples of GH-diverging LLS to outline key requirements
 .
