Hi Georges,
if you start from OMs as basic, then a branch is a set of OMs (only
"consistent"/ordered set ?). Then it means a branch is unique. Some part of
different branches could overlap, but as I don't understand what could be an
absolute measure (meaning it never change and is fixed forever) between all
branches, I don't see how to assert the measure of a branch... Also viewing
from this point each 1st pov "lives" in its own branch (as a branch is an
ordered set of OMs which in turn is associated to a 1st person).
