A comment on notation:
In the literature, X has been used for decades to denote an
appropriate connective cover of a space (or spectrum) X. Exactly WHAT
cover seems to vary. For example, glancing through random stuff in my
office reveals many folks for whom X is the n-connected cover, and
many others for whom X is the n-1 st connected cover. (E.G. My
random sampling has Fred Cohen in the first camp, and Mark Mahowald in
the second, and the issue didn't come up in their joint papers.)
I am guessing that X is n-connected was historically first. Can
anyone verify this?
And then those who use X to be n-1--connected realized the first
guys got it wrong. (History?) And I concur. In fact, I would like to
use this list to speed up this mutation of notation.
Thoughts?
