PR triaging:
- second countable, clopen PR 797
-
local_base
: the neighborhood is equal to thefilter_from
ofB
-
topological_base
: there is an alternative definition - maybe this could be merged as it is with the current definition
- even keep the definition and add the other definitions with lemmas for the equivalence
- what about the idiom
cid (iffLR (exists2P _ _) (h n))
?- put a name for all these idioms is not reasonable
- TODO: maybe put this somewhere in the wiki
- TODO: try to use
sigW
(one layer of abstraction on top ofcid
) instead ofcid
(the axiom)

- Product embedding PR 768
- question about displays for the
open
predicate (see https://github.com/zstone1/analysis/pull/2/commits/0e639029ceb6ce6a6bcdf7cafd05f55c577c47a7)- see l.6728:
@open weakT
? add a notation to print@open weakT
asweak_open
- see l.6728:
- same for supremum, with a local notation ("print only" notations)
- just notations for this PR, no displays
- wait for a tool might be the best solution but for topology we maybe cannot wait
- putting displays would be needed for topologies only, no need to add displays for normed spaces and higher in the hiearchy
- question about displays for the
- integral of constant and generalization of
le_integral_abse
PR 781- TODO: expose both lemmas
- rename the second, more general lemma with
comp_abse
- put Cyril as a reviewer

Easy PRs:
- naming, following discussion of an issue, PR 767
- TODO: avoid
(d : _)
by replacingVariables
withContext
- TODO: avoid
- add a lemma to
classical_sets.v
PR 791- TODO: merge
- fix generated sigma-algebras of extended real numbers PR 793
- collision of naming with when there are two notions of infinity
- notation is not correct for lattices with a bottom and a top
- don't know of a good fix yet
- forbid interval with infty bounds using a trick similar to
nonProp
, a type that can only be instantiated by something which is not proposition: https://github.com/coq/coq/blob/master/theories/ssr/ssreflect.v#L30-L34

- see also issue 795
- fix deprecated declarations PR 798
- we need to make the proxies...
- this should be fixed at the the Coq level
- send to the Coq call?

RFC:
- in a previous meeting [2022-02-24] we concluded that the complex exponential is better defined as a power series
PR 770 does so and prove
exp x%:C = (expR x)%:C
it requires undesirable type constraints (: complex_ringType _
) how to tackle expD?- TODO: Cyril to look at it
