DESCRIPTION:Speakers: Boris Vertman (Uni Oldenburg)\n\nMelrose’s geometr
 ic microlocal analysis involves the concept of blowing up\nsubmanifolds to
  resolve non-uniform operator kernel behaviour. This technique has\nbeen c
 entral to the analysis of singular spaces\, but was previously disconnecte
 d\nfrom discrete geometry. We introduce a new framework that applies Melro
 ses's blowup\ntechniques to scaling limits of discrete surfaces to study t
 he discrete heat kernel\nas the discretization mesh size goes to zero. Thi
 s proves a full asymptotics of the\ndeterminant on discrete surfaces beyon
 d the example of regular lattices that has\nbeen the best possible result 
 so far.\n\nhttps://math-events.uni-bonn.de/event/1426/
