Participants: Marie, Cyril, Kazuhiko, Reynald

  • postponed topics:
  • TODOs:
    • about PR 205
    • about PR 224 (integral sketch)
      • TODO(reynald): PR the new lemmas about sequences of extended reals that are lingering at the top of measure_wip.v
    • TODO(reynald): investigate redundancy between summability.v and isum from measure_wip.v (branch integral_sketch_hb)
    • TODO(marie): PR Banach-Steinhaus and Baire's theorems (https://github.com/tvignon/StageL3)
      • the first goal is to integrate some notions into master (closed balls, fixes for working with floor, etc., density)
      • reuse the notion of boundedness from master (instead of defining locally boundedness for linear functions)
      • the statement of Baire's theorem can be improved
    • TODO(marie): PR Hahn-Banach (https://github.com/math-comp/analysis/pull/179) into master
    • TODO(reynald): measure_wip.v: set_of_interval should use mem
    • TODO(reynald): create a FAQ with an entry on using Boolean operators with Coq's Reals
