Homology concordance and an infinite rank free subgroup
نویسندگان
چکیده
Two knots are homology concordant if they smoothly in a cobordism. The group C ? Z (respectively, ) was previously defined as the set of spheres that bounds balls S 3 ), modulo concordance. We prove / contains ? subgroup. construct our family examples by applying filtered mapping cone formula to L-space knots, and linear independence with help connected knot complex.

Infinite Loop Spaces with Odd Torsion Free Homology
It is shown that an infinite loop space with no odd torsion in its integral homology also has no odd torsion in its homotopy. Combined with known results of Steve Wilson, this gives a complete classification; all such spaces are products of the Wilson spaces, which are the building blocks of the spaces in the omega spectrum for BP .
متن کاملKnot Concordance and Homology Cobordism Workshop
I will give an overview of the n-solvable filtration of the smooth knot (or string link) concordance group including the strategy and tools used to analyze it: higher-order Alexander modules, linking forms and signature defects. I will attempt to discuss what is known about this filtration, what is not known but should be knowable by present techniques; and discuss the failings of present techn...
متن کاملAutomorphisms of a Free Group of Infinite Rank
The problem of classifying the automorphisms of a free group of infinite countable rank is investigated. Quite a reasonable generating set for the group AutF∞ is described. Some new subgroups of this group and structural results for them are presented. The main result says that the group of all automorphisms is generated (modulo the IA-automorphisms) by strings and lower triangular automorphisms.
متن کاملGroups with Infinite Homology
A group is said to be acyclic if its reduced homology vanishes. Many interesting classes of groups have been discovered having this property ([2] is a useful survey). This is an indication that the reduced homology carries limited information. Here we obtain information about H̃(G) for a class of groups G that includes all locally finite groups and all soluble groups of finite rank. We show that...
متن کاملExamining Economic Convergence Using Rank Concordance Indices
Recent research has suggested the use of binary and multi-annual rank concordance indices as measures of β-convergence. Using numerical analysis, it is shown that this approach has severe limitations. In particular, it is shown that hypothesis testing based upon the binary index possesses an inherent bias towards non-rejection of the null, leading to spurious detection of β-convergence. The pro...
