CohenCyril closed Issue #165 Canonical structures on a given type:

How could we construct a tool which would unveil all the canonical structures on a given type at some point in a Coq file ? Could the hierarchy builder tool help ?(https://github.com/math-comp/hierarchy-builder) Could we build automatically a graph of the canonical declarations of structures and their dependencies ?

This seems crucial when using mathcomp analysis libraries, where one uses regularly the basic properties of a type endowed with much richer structure.

vlj opened PR #206 Add a distrLattice canonical structure to set T. from `subset-lattice`

to `master`

:

Hi,

This add a canonical distrLattice structure to setT and subset relation.

I have far less experience in adding a canonical structure than I have writing lemma so the PR is likely a bit rough, any guidance is appreciated.Some comments:

- For some reasons coq fails to unify the type of the lemma setU setI ... when passed as argument to MeetJoinMixin. I added "wrapper lemma" SetOrder_setCI SetOrder_setCU ... to force the type. I'm not sure this is the right thing to do (I could also use @setU (set T) directly in the argument but it would be quite hard to read) and the naming is maybe wrong.
- subset is a Prop while distrLattice expects a rel (ie result type is bool). I wrapped the subset relation in asboolsubset. This means that to use lemma in order (like in my case ltux) one need to map subset and asboolsubset forth and back so I provided subsetE. I don't know if it's the usual idiom.

affeldt-aist milestoned Issue #206 Add a distrLattice canonical structure to set T.

Hi,

This add a canonical distrLattice structure to setT and subset relation.

I have far less experience in adding a canonical structure than I have writing lemma so the PR is likely a bit rough, any guidance is appreciated.Some comments:

- For some reasons coq fails to unify the type of the lemma setU setI ... when passed as argument to MeetJoinMixin. I added "wrapper lemma" SetOrder_setCI SetOrder_setCU ... to force the type. I'm not sure this is the right thing to do (I could also use @setU (set T) directly in the argument but it would be quite hard to read) and the naming is maybe wrong.
- subset is a Prop while distrLattice expects a rel (ie result type is bool). I wrapped the subset relation in asboolsubset. This means that to use lemma in order (like in my case ltux) one need to map subset and asboolsubset forth and back so I provided subsetE. I don't know if it's the usual idiom.

CohenCyril demilestoned Issue #206 Add a distrLattice canonical structure to set T.

Hi,

This add a canonical distrLattice structure to setT and subset relation.

I have far less experience in adding a canonical structure than I have writing lemma so the PR is likely a bit rough, any guidance is appreciated.Some comments:

- For some reasons coq fails to unify the type of the lemma setU setI ... when passed as argument to MeetJoinMixin. I added "wrapper lemma" SetOrder_setCI SetOrder_setCU ... to force the type. I'm not sure this is the right thing to do (I could also use @setU (set T) directly in the argument but it would be quite hard to read) and the naming is maybe wrong.
- subset is a Prop while distrLattice expects a rel (ie result type is bool). I wrapped the subset relation in asboolsubset. This means that to use lemma in order (like in my case ltux) one need to map subset and asboolsubset forth and back so I provided subsetE. I don't know if it's the usual idiom.

CohenCyril submitted PR Review for #223 Boole inequality.

CohenCyril created PR Review Comment on #223 Boole inequality:

Statements of

`{homo : ... }`

or`{mono : ...}`

shouldn't be named after`homo`

, or`mono`

, just as for`{morph ...}`

lemmas. Instead please use the head of the unfolded statement (for homo) or the head of the LHS of the equality (for mono). In this case:`sub_bigUB_of`

.

CohenCyril submitted PR Review for #223 Boole inequality.

CohenCyril created PR Review Comment on #223 Boole inequality:

When a

`mono`

lemma subsumes`homo`

, it gets priority for the short name, and if really needed the corresponding`homo`

lemma can be suffixed with`W`

. If the`mono`

lemma is only valid on a subdomain, then the`homo`

lemma takes the short name, and the`mono`

lemma gets the suffix`in`

.

(This should all be added to CONTRIBUTING.md I guess)

This is wrong.

pi8027 created PR Review Comment on #205 Topological structures on numfields:

This

`Canonical`

declaration makes`numFieldType`

inheriting from`pointedType`

, but by construction rather than inclusion. Actually, this can be generalized to make`zmodType`

inheriting from`pointedType`

, and then you have to declare unification hints between`Pointed.sort`

. Even if you do not generalize it, similar unification hints for`numClosedFieldType`

,`realFieldType`

,`archiFieldType`

The above

We cannot really remove

since it is in core mathcomp and useful there. Actually, all the results about`^o`

So we have the following ambiguous paths here:

`New coercion path [numField_comAlgType; GRing.ComAlgebra.comRingType] : Num.NumField.type >-> GRing.ComRing.type is ambiguous with existing [Num.NumField.comRingType] : Num.NumField.type >-> GRing.ComRing.type. [ambiguous-paths,typechecker]`

I think the problem is twofold:

`regular_comRingType`

uses`GRing.mulrC`

, which is opaque.- Since
`lalgType`

and its subclasses do not take the ring structures as their base, an eta expansion appears in the former path.

`'d_a f x / x`

although valid is a non canonical way for getting the coefficient of a linear map (no need to take a limit by the way, it is supposed to be constant). The canonical way is to first take the Jacobian (using lin1_mx) and in dimension 1 (since R^o is), just take the only coefficient: jacobian f 0 0.

`Landau notations can be written in four shapes: - `f =o_F e` (i.e. functional with a simple right member, thus a binary notation) - `f = g +o_F e` (i.e. functional with an additive right member, thus ternary) - `f x =o_(x \near F) (e x)` (i.e. pointwise with a simple right member, thus binary) - `f x = g x +o_(x \near F) (e x)` (i.e. pointwise with an additive right member, thus ternary) The outcome is an expression with the normal Leibniz equality `=` and term `'o_F` which is not parsable.

. _This is the preferred way of stating a convergence._Lemmas about it use the string`cvg`

converges and defaults to a distinguished point otherwise. _It should only be used when there is no other expression for the limit._Lemmas about it use the string`lim`

.`cvg F`

is defined as`F --> lim F`

Depends on #223 (EDIT by Cyril) which has been merged in master

drouhling closed without merge PR #112 WIP / Experiment : Remove the dependency on R.

CohenCyril milestoned Issue #112 WIP / Experiment : Remove the dependency on R:

I need feedback on this branch which:

replaces

`ball`

with`entourages`

as primitive for the definition of`uniformType`

.removes

`absRingType`

and uses`numDomainType`

instead (related to #4).instantiates the hierarchy on mathcomp's algebraic structures (see

`classical_sets.v`

and`hierarchy.v`

).replaces

`R`

from standard library with any`realFieldType`

/`realType`

and`Rbar`

with`realFieldBar`

.moves non norm-related structures to

`topology.v`

.Using entourages tends to lengthen proofs. In particular, I am not very satisfied with the way

`entourages_split`

replaces`ball_split`

but I haven't found any solution yet.

In normed spaces it is less problematic since we can still use the balls defined by the norm.This branch only use a small part of

`Rstruct.v`

, and this part does not depend on`R`

any more. I believe this file should move to`misc/`

, be extended with the structures from our hierarchy, and come with an example file on`R`

containing the compatibility lemmas from Coquelicot about`continuity_pt`

and`derive_pt`

.The file

`derive.v`

also takes a very long time to compile. I mean more than before. I don't know why yet. In particular Coq takes a long time to go through the proof script of`diffM`

. I looked at the debug script for typeclasses and it seems that Coq is stuckaftertypeclass inference finds how to close all generated subgoals.TODO-list:

[x] Generalize

`ereal`

and merge with`realFieldBar`

(related to #3).

`ereal`

is now generalized to any`numDomainType`

and used everywhere. The`+oo`

and`-oo`

notations replace`\+inf`

and`\-inf`

.

I suggest to delete`Rbar.v`

but first we need to finish the discussion in #3: does there remain any part of the arithmetic in`Rbar.v`

we want to port to`ereal`

Â ?[x] Move

`bigmaxr`

theory out of`Rstruct.v`

? Or reimplement using`bigop`

, generalizing and extending`bigRmax`

theory ?A theory of min/max using

`bigop`

is now in`hierarchy.v`

. This is probably not perfect and should be extended (see discussion in #114), but it is sufficient for the purpose of this PR.[x] Move

`Rstruct.v`

to`misc/`

and extend it with our structures.[x] Reintroduce commented out lemmas about

`R`

and`Rbar`

, either translating them to`realFieldType`

/`realType`

/`realFieldBar`

or putting them in an example file in`misc/`

.[ ] Investigate

`derive.v`

's compilation issue.[ ] Clean up.

[x] Be consistent with names (sometimes

`entourages`

is used, sometimes it is`entourage`

).[x] Rework the existing documentation.

[ ] Rename

`hierarchy.v`

(and`topology.v`

?) to reflect the new organization.[x] Make sure each lemma is in the right file and no lemma has been dropped.

Actually, on second thoughts, this definition would be even more usable like this:

`Definition proper_subset {A} (X Y : set A) := (X `<=` Y) /\ (exists2 a, Y a & ~ X a).`

With lemma

`proper_neqAsubset : (X `<` Y) = (X `!=` Y) /\ (X `<=` Y)`
