On Generalized Homology of Artin Groups

Journal of Mathematical Sciences, 2003
Generalized braid groups \(\text{Br}({\mathcal D}_\infty)\), \(\text{Br}({\mathcal C}_m)\) and \(\text{Br}^g_\infty\) (braids of an infinite number of strings in a genus \(g\) handlebody) are considered and the Morava \(K\)-theory \(K(n)_*(\text{Br}({\mathcal D}_\infty))\), \(K(n)_*(\text{Br}^g_\infty)\), the Brown-Peterson homology \(\text{BP}_*(\text{

Homology Groups of Relations

The Annals of Mathematics, 1952
Any relation between the elements of a set X and the elements of a set Y is associated with two simplicial complexes K and L. A simplex of K is a finite set of elements of X related to a common element of Y; a simplex of L is a finite set of elements of Y related to a common element of X.

Character Group of a Relative Homology Group

The Annals of Mathematics, 1940
If L is a subcomplex of a finite complex K, the topologically invariant factor group of the group of p-cycles of L bounding in K taken with respect to the subgroup of those bounding in L is useful in topology. The principal aim of this paper is to find its character group and to interpret the character group geometrically (theorems 4.2 and 4.4 at the ...

Abelian Groups with a Vanishing Homology Group

Canadian Journal of Mathematics, 1969
In this paper, we wish to characterize those abelian groups whose integral homology groups vanish in some positive dimension. We obtain a complete characterization provided the dimension in which the homology vanishes is odd; in fact, we prove that the only abelian groups which possess a vanishing homology group in an odd dimension are, up to ...
