Abstract/Media

The Hanna Neumann Conjecture from 1956-1957 asserts a specific upper bound on the rank of the intersection of two finitely generated subgroups in a free group. Walter Neumann proposed a strengthened version of the Hanna Neumann Conjecture (SHNC) in 1989-1990. We will present several points of view of SHNC and sketch its proof in two
languages: graph theoretic and analytic.

(In case you miss this talk, two talks on SHNC will be given at UC Berkeley on October 5.)
