- issue https://github.com/math-comp/analysis/issues/157 about the documentation of filters
- about the 1st point: define what is "canonical"
- about the 2nd point:
- we have overloading: we first coerce using the element and then infer the filter
- the goal is to be able to talk about a limit of a filter in R while covering both the finite and the infinite case, as in convergence in \bar R
- TODO: provide an example to solve this issue
- maybe not used yet in fact, put as undocumented until there is an actual use
- LT: document the fact that it is a read-only notation
-
https://github.com/math-comp/analysis/pull/411 (is_interval large inequalities)
- OK to merge
-
https://github.com/math-comp/analysis/pull/374 (dual real)
-oo + +oo = +oo
- CC: notice a problem with scopes
- TODO: CC to do the review after a fix by PR
- put a link to the development that uses this feature as part of the documenting header?
- CC: put Coq developments depending on MathComp-Analysis in nix and coq-packages to have the CI check the dependencies
- see README in https://github.com/coq-community/coq-nix-toolbox
-
https://github.com/math-comp/analysis/pull/438 (T0, T1)
- TODO: reformat definitions and double-check statements
- ZS: raise a more general question, use filter meet for these definitions?
- CC: favor filter definition, equivalence with the same description in terms of sets
- TODO: merge almost as is, just do reformatting
- TODO: RA to review
-
https://github.com/math-comp/analysis/pull/311 (domain restriction)
- CC have a completed branch and just need to update the changelog
- NB: ZS unavailable for the next two weeks
- the patch function should replace fer in the PRs on integration
-
https://github.com/math-comp/analysis/pull/410 (subspace)
- CC has almost completed his review
- this PR can be uses in the "continuous inverse PR" to replace continuity on a segment but there is no need to be delay the merge, this can be fixes later
- ZS: see also https://github.com/math-comp/analysis/issues/408 to weaken the statement of the mean value theorem using continuity at the end points but on the subspace topology
-
https://github.com/math-comp/analysis/pull/385 (continuous inverse)
- TODO: update changelog, put the right lemmas in the right places, create a
realfun.v
file, before merging the trigo PR - TODO: AR to commit
- TODO: update changelog, put the right lemmas in the right places, create a
-
https://github.com/math-comp/analysis/pull/383 (trigo)
- most things to go in
realfun.v
- TODO: get rid of names with prime suffixes
- CC: it is only about R for the exponential? LT: yes
- some things could be subsumed by power series (notation of radius of convergence, etc)
- TODO: ping TS about that and report on Zulip
- ZS: the Arzela-Ascoli PR contains some related elements
- most things to go in
-
https://github.com/math-comp/analysis/pull/434 (density of rat)
- rename archimedean
- prove the relation with the dense predicate, it should be 5 lines
- TODO: AR
-
https://github.com/math-comp/analysis/pull/435 (rat is countable)
- redundancy with domain restriction
-
leq_card
predicate should be better defined - should be merged after the domain restriction PR
- inclusion in the Coq platform?
- see messsage on Zulip and also https://github.com/coq/platform/issues/21#issuecomment-929068379
- as "full"
- a quick work about getting rid of the type classes by CC
- approach: copy the infrastructure for subalgebra (submodules, etc.) predicaates from MathComp
- TODO: AR to release 0.3.11
-
https://github.com/math-comp/analysis/pull/398
- lra to realType
- it is not parametrical yet, it is based on a certificate, no relation with mczify
- just work with the R in RStruct as of today
- lra to realType
