In the ongoing discussion around Boolean rings and
algebras, something is embarrasing: it seems that
the sides are not going to agree on concrete
mathematical facts.
It perhaps would be useful if someone among those
thinking that BR and BA *are* isomorphic, PRESENTS
a CONCRETE, well defined isomorphism
(well defined in terms of ordinary algebra, not using
special categorical notions which many do not understand
and look at as a kind of generalized habbracadabbra,
that is, an isomorphism should be a map, for which the
domain, the range, and the action of the map itself,
must be well defined),
together with some clear arguments WHY the thing
presented is called an isomorphism despite the
signatures are different.
Hopefully this should not require long space.
