4:00 pm Monday, March 30, 2009 Topology Seminar: 2-Torsion in the n-solvable filtration of the knot concordance groupby Tim Cochran (Rice) in HB 427- Tim Cochran (Rice) (joint with S. Harvey and C. Leidy) We will review some basics about what is known about the knot concordance group, in particular about elements of finite-order; and the n-solvable filtration. Our new result is that in each integral term of the associated graded of this filtration, there is a an infinite product of Z-mod-twos.
