DESCRIPTION:Title: <a href="https://researchseminars.org/talk/jomarec/36/"
 >The interplay of mathematics and numerics in understanding naked singular
 ity formation in critical collapse</a>\nby Carsten Gundlach (University of
  Southampton) as part of JoMaReC - Joint Online Mathematical Relativity Co
 lloquium\n\n\nAbstract\nI will give an overview of numerical evidence that
  codimension one-sets of smooth initial data for matter coupled to GR form
  naked singularities - from scalar fields and fluids in spherical symmetry
 \, where the evidence is strong\, to vacuum GR\, where the evidence is sti
 ll confusing\, but at least now beginning to be agreed by independent code
 s. Can one hope to prove some form of this naked singularity conjecture? I
 n the last ten years or so\, there has been considerable mathematical prog
 ress on the existence and stability of smooth self-similar blowup solution
 s in dispersive PDEs\, and on naked singularity formation in GR. I will hi
 ghlight some of these papers that particularly interest me as steps on the
  way to a future proof of naked singularity formation from codimension-one
  smooth initial data.\n
