DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GoeTop/15/">
 Topology of spaces of loops</a>\nby Andreas Wagenblast (University of Göt
 tingen) as part of Göttingen topology and geometry seminar\n\n\nAbstract\
 nIn my talk I will start with a brief introduction to configuration spaces
  and some basic results (e.g. the natural projection $PB_n\\to PB_{n-1}$\,
  by forgetting the $n$-th puncture\, is known to be a fibration. This fact
  is no longer true for the pure untwisted rings/wickets). After that I wan
 t to explain the geometric method of Brendle and Hatcher\, explained in th
 eir 2010 paper titled *Configuration Spaces of Rings and Wickets* for comp
 uting some of the fundamental groups and demonstrate this on some examples
 . There is\, however\, a limitation of this procedure\, i.e. the method do
 es not imediately apply to *pure untwisted wickets*. In the last part of m
 y talk I will point out this problem and indicate a (hopefully possible) s
 olution to this\, which (if it works out) in the end will be some of my re
 sults of my master thesis.\n
