  • quick summary about the branch mathcomp_master_sequence
    • we limit ourselves to elementary results and will generalize later
      • elementary but using filters (epsilon-delta reasoning recovered with lemma cvg_normW)
  • what we put in milestone 0.3
  • temporary policy for merges
    • merge even if results could be generalized but put a TODO in the code and an issue pointing at this TODO
  • discussion about the introduction of a metric layer (not now)
  • discussion about the integration of complexes
  • revive https://github.com/math-comp/analysis/pull/119
    • add uniform spaced between topological spaces et pseudometric spaces
    • later: change pseudometric with balls to a pseudometric with a distance function
      • a structure with a distance evaluating to +oo might be bothersome
  • details about https://github.com/math-comp/analysis/pull/187 on sequences
    • question about differential of inverse in derive.v
      • differential_Rinv has been updated
      • Cinv_continuous for complex numbers in normedtype.v
    • poll about cvg vs. is_cvg (cvg wins)
    • reminder about new namings
      • in particular, cvg_normW changed to cvg_distW, in anticipation of the introduction of a notation similar to | - _ |%N for ssrint once distances are introduced
    • explain the definition of series
      • notation [normed series u_] that replaces the general term with its norm
    • next step: uniform convergence
      • introduction a type of function bounded on a domain?
  • discussion about metrizable spaces
  • You've been warned: don't use exact, done or by in Hint Extern, prefer solve[...]
