TRIANGLE GEOMETRY/TOPOLOGY SEMINAR
FIRST ANNOUNCEMENT
DATE:
LOCATION: Hempfield High
School,
Room 213 (directions attached)
followed by dinner at a place to be determined.
"Free symmetry ranks of spheres and products
of spheres"
ABSTRACT: This will be an expository talk by a
non-expert on the question of
which
finite groups G can act freely on the manifolds S^n,
(S^n)^k and
S^{n_1} x
... x S^{n_k}.
In the first two cases, the question has been
well
explored, and the answer depends primarily on the rank of G, where
rk(G) = max_{n \in N} (for
some prime p)(Z_p)^n \subset G. I was led
to explore aspects of the third question last spring, and
learned about
an (old)
example showing the situation to be more complicated than I had
originally
guessed.
I expect to discuss, or at least
mention, results of Smith, Milnor, Adem,
Browder, Carlsson
and Oliver, among others (but probably not McCooey).
EVERYONE WELCOME
