DESCRIPTION:Title: Odd Moebius—Kantor Ring Puzzles\n\nAbstract: Moebius—Kan
 tor complexes were introduced by Barré and Pichot to serve as a canonical 
 family of spaces of “intermediate rank”\, in an attempt to shed light on t
 he flat-closing conjecture. They form a rich family of locally-defined CAT
 (0) spaces with interesting flat geometry\, and can be distinguished up to
  isomorphism by an invariant called the parity. In this talk\, we give an 
 introduction to Moebius—Kantor complexes and report on a recent work by Ba
 rré\, Pichot\, and myself classifying the odd ring puzzles associated with
  them. These are tessellations of the Euclidean plane with local condition
 s constraining the set of admissible neighbourhoods\, arising as embedded 
 flat planes in our complexes.\n\nWe will gather for teatime in the lounge 
 after the talk. Note that this will be the last talk of the semester.\n\n
