Re: Siegfried's recent paper, and other matters
Nate,
Writing an appendix to the standard seems to me too early: In order to
vote for an appendix, we certainly need to see how it will be
integrated within the standard, which is too early since the standard
is not yet completely settled. This is the reason why we vote on
motions instead, which are independent and self-contained and will be
used to guide writing the standard.
I therefore recommend instead writing a motion, detailing definitions
related to Kaucher intervals and their related operations proposed be
included in this appendix. This will help focussing on the content
instead of the form...
I think furthermore several issues should be addressed before any
detailed appendix or implementation is discussed. For example:
1- Will the operations over Kaucher interval be restricted to bounded
Kaucher intervals?
2- What correspondance will be provided between the classical empty
set and Kaucher intervals?
3- How to compute operation with Kaucher interval that are not
included in the domain definition of the functions?
4- How to compute reverse operation on Kaucher intervals?
Regards,
Alexandre
