SUMMARY:Topology Seminar Series
DESCRIPTION:
Title: Knot concordance and homology sphere groups\n
Speaker:
Kyle Larson, MSU\n
We introduce
the knot concordance group and various homology
sphere groups constructed from 3-manifolds,
and discuss two homomorphisms to the rational
homology sphere group. If B denotes the homomorphism
from the concordance group defined
by taking double branched covers of knots,
we show that the kernel of B is infinitely generated.
We also study the inclusion homomorphism
P from the integral homology sphere group.
Using work of Lisca we show that the image
of P intersects trivially with the subgroup
generated by lens spaces. This is joint work
with Paolo Aceto.\n\n
