Subject:  This year's algebraic topology in the mathematics arXiv

For some reason math.AT (Algebraic Topology) has picked up a bit in
the mathematics arXiv this month.  So I am taking the occassion to
list the articles in this category since the beginning of the year.
Of course many people check regularly, and others subscribe to the
regular e-mail announcements.  But some find these to be too
much of a bother.  Of course if you want to check yourself, I recommend
the Front:

AT is a popular category for cross-listings, but here I am taking
a narrow interpretation and listing only articles primarily listed
as math.AT.  Personally I am very pleased to see serious-looking
articles in the math arXiv in areas that are neither close to physics
nor to my own areas.  I suppose that I have developed an alliegance
to mathematics, because it is much less gratifying for me to see the arXiv
spread to new areas of physics, for example.
