• Quiver and standard operations for monodromic perverse sheaves on a trivial line bundle

• Line fields on manifolds

• Homotopy limits and fixed point stacks
  This is a more general (but not quite as elementary) version of `On fixed point stacks' below. A version halfway between the two may be found here.
• On fixed point stacks
• A remark on Ehresmann's fibration theorem
• Fixed points and Langlands parameter spaces for real groups
• Discussion around integration along the fiber
• Discussion around integration along the fiber for motivic sheaves (complex varieties)

These are mainly short notes I wrote for myself that I think are coherent enough for 3rd party consumption. Nothing here is intended for official publication. Some will end up on the arXiv as permanent repository.
