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
