whew; back to the old format, which is good, since
it was impossible to see the "tree" in "v2."
the main point is that the folks
who use p-adics blithely assume that
the string of b-1s (in base-b) do continue,
"out to infity to the left of the decimal," although
that "point" is superfluous, except as a kind
of reminder. just like one assumes
about the underflow condition on the calculator,
subtracting a larger numger from a smaller;
one always has to make sure that it wasn't just the tail-end
of a very long string of 9s.
anyway, if that was an apt characterization
of Escultura's method, then it seems to be akin
to AP's. if that is so, then it seems to be
outside of the bounds of common-sense, since
Fermat clearly meant the "last" theorem in terms
of Diophantus, which does not include the subject
of "p-adic valuations" -- not that I've read every thing
about it.
but they're reputedly good for other stuff --
that is not *only* known to AP, I guess.
