Participants: Alessandro, Georges, Pierre, Quentin, Reynald, Takafumi
- which keywords to add to opam files?
- see PR 1125
- about the release of MathComp-Analysis 1.0.0
- the documentation of the HB branch needs to be updated
- main problem is
topology.v
- shall we release 1.0.0 without the doc updated?
- no
- what to do for
topology.v
?- put the list of structures first
- then put the notations
- TODO:
- Reynald will do a first pass (before the end of next week)
- Takafumi will do a second pass (interested in documented filtered types)
- hard deadline for the release: mid-January 2024
- release of MathComp-Analysis 0.6.7 before Christmas
- TODO: issue about the funny title (* The algebraic part of the algebraic hierarchy *)
- PR by Takafumi https://github.com/math-comp/analysis/pull/1117
- Zorn's variant:
- localized version where the maximal element is taken over a given point
- stated for relations in Prop
- stronger than the original Zorn's lemma
- no link with the Zorn lemma by Georges
- the latter is a bit stronger because it is localized to subsets
- only require a preorder and not a partial order
- similar to the already present
ZL_preorder
in fact
- similar to the already present
- Quentin has ported Georges' Zorn's lemma
- there is also
Zorn_bigcup
- NB(rei): used in
ex_maximal_disjoint_subcollection
which is used in Vitali's lemma
- NB(rei): used in
- maybe derive the Prop version from the bool version
- but this require PR #1119 first...
- Conclusion: issue postponed
- Zorn's variant:
- PR #1119 (adding a
contraposition
tactic)- quick demo by Quentin
- Georges had a work about the implementation
- Quentin has a couple of TOTHINK
- do not use exfalso for consistency
- 8.12 issue still need to be addressed
- MCA is adequate because it is a tactic for a Prop irrelevant setting
- it would require more work for a MathComp version
- TODO: Quentin to complete the PR with the doc so that it can be reviewed lightly in January
- making classical a standalone library
- idea by Yves for use in liberabaci among others
- coq-mathcomp-classical is already a package
- TODO: Takafumi to come up with ideas to improve the presentation of the webpage
- recorded as issue https://github.com/math-comp/analysis/issues/1126
- documentation using coq2html:
- here is a PR that does minimal changes https://github.com/math-comp/analysis/pull/1108
- TODO: pierre to double-check
- the result can be seen: https://yoshihiro503.github.io/coq2html/
- still a few bugs but it does not use sed and allows for markdown
- drop coqdoc for the next release?
- yes
- other issue related to documentation: https://github.com/math-comp/analysis/issues/1071
- rename to
rocq2html
? - TODO(rei): contact Xavier
- here is a PR that does minimal changes https://github.com/math-comp/analysis/pull/1108
- PR triaging:
-
https://github.com/math-comp/analysis/pull/1029 (adapting) -> Pierre?
- closed (problem forgotten, not needed anymore apparently since CI is happy)
-
https://github.com/math-comp/analysis/pull/1121 (lim sup)
- TODO: review asked to Zachary
-
https://github.com/math-comp/analysis/pull/1083 (radon nikodym chain rule)
- TODO: Quentin will take a quick look (keeping in mind that we have extra notations for HB on Coq 8.14 and 8.15 and that we might need a notation for
ae_eq
) - TODO: will also ask Zachary afterwards
- TODO: Quentin will take a quick look (keeping in mind that we have extra notations for HB on Coq 8.14 and 8.15 and that we might need a notation for
-
https://github.com/math-comp/analysis/pull/1122 (easy fix but that raises the question of the status of
forms.v
)- try to remove
mulr_rev
in favor ofR^C
(putR^C
in the canonical, cast one of the arguments to the converse ring) - Takafumi: is there a morphism defined from
R
toR^C
?- Shouldn't be too hard
- try to remove
-
https://github.com/math-comp/analysis/pull/1029 (adapting) -> Pierre?
- Poll for the next meeting: https://framadate.org/XMI2ZG5hAIoNdhjD
