Peripheral elements in reduced Alexander modules

چکیده
We discuss meridians and longitudes in reduced Alexander modules of classical virtual links. When these elements are suitably defined, each link component will have many meridians, but only one longitude. Enhancing the module by singling out peripheral provides a significantly stronger invariant. In particular, enhanced determines all linking numbers link; contrast, alone does not even detect how 0.

Alexander Modules of Irreducible C-groups
A complete description of the Alexander modules of knotted n-manifolds in the sphere S n+2 , n ≥ 2, and irreducible Hurwitz curves is given. This description is applied to investigate properties of the first homology groups of cyclic coverings of the sphere S n+2 and the projective complex plane CP 2 branched respectively alone knotted n-manifolds and along irreducible Hurwitz (in particular, a...
متن کاملA Discussion of Higher-Order Alexander Modules
We will discuss a technique to distinguish knots via an algebraic invariant, namely the Alexander module, which is a module associated to the universal abelian cover of the complement of a knot. We will present a generalization of the Alexander module by constructing modules corresponding to different regular covering spaces of the knot complement. We will present a numerical invariant that can...
متن کاملTangential Alexander Polynomials and Non-reduced Degeneration
We introduce a notion of tangential Alexander polynomials for plane curves and study the relation with θ-Alexander polynomial. As an application, we use these polynomials to study a non-reduced degeneration Ct, → D0 + jL. We show that there exists a certain surjectivity of the fundamental groups and divisibility among their Alexander polynomials.
متن کاملIntersection Homology and Alexander Modules of Hypersurface Complements
Let V be a degree d, reduced hypersurface in CP, n ≥ 1, and fix a generic hyperplane, H. Denote by U the (affine) hypersurface complement, CP−V ∪H, and let U be the infinite cyclic covering of U corresponding to the kernel of the linking number homomorphism. Using intersection homology theory, we give a new construction of the Alexander modules Hi(U ;Q) of the hypersurface complement and show t...
متن کاملR-MODULES FOR THE ALEXANDER COHOMOLOGY THEORY APPROVED: Major Professor
The Alexander Wallace Spanier cohomology theory associates with an arbitrary topological space an abelian group. In this paper, an arbitrary topological space is associated with an R-module. The construction of the R-module is similar to the Alexander Wallace Spanier construction of the abelian group. In Chapter I, the algebraic and topological material necessary to construct the theor'y is lis...
