Sometime ago Alex Simpson advertised a paper
"Comparing cartesian closed categories of (core) compactly generated
spaces". http://www.cs.bham.ac.uk/~mhe/papers/ELS03.pdf
where we have the same question (problem 9.2). Hence if anyone has an
answer, please forward it to us as well - thanks.
(I also take the opportunity to mention that we have updated the paper
with some references given to us by some members of this list, in
Section 3.)
