WEEK 9

Can spinors be combed?...

We started with several simple reflections:

  • The sum of the curvatures of two tangent disks is an Eulerian sum of squares due to the "Norm Theorem" (see the comix-like illustration from the previous meeting)
  • Thm 6 = Thm 7  (visualized by continuous transformation) 
  • If two adjacent spinors in an Apollonian disk packing are integral, so are all spinors in the packing.

 Then we defined "tuned spinors" and parallel transport of signs.
