Functoriality, Smith theory, and the Brauer homomorphism
-- David Treumann, September 19, 2014
<p>
I will discuss some results relating mod p
cohomological automorphic forms on groups G and H, when H is
the fixed points of an automorphism of G of order p. The
results are obtained via Smith theory, an old technique in
algebraic topology. No knowledge of automorphic forms or
Smith theory will be assumed. Based on joint work with
Venkatesh.
