The Quandle and Group for General Pairs of Spaces
نویسنده
چکیده
Joyce has shown that the fundamental quandle of a classical knot can be derived from consideration of the fundamental group and the peripheral structure of the knot, and also that the group and much of the peripheral structure can be recovered from the quandle. We generalize these results to arbitrary dimensions, and also to virtual and welded knots and arcs.

An Algebraic Approach to Symmetry With Applications to Knot Theory
The usual algebraic construction used to study the symmetries of an object is the group of automorphisms of that object. In many geometric settings, however, one may interpret the symmetries in a more intimate manner by an algebraic structure on the object itself. Define a quandle to be a set equipped with two binary operations, (x,y) ↦ x ▷ y and (x, y) ↦ x ▷-1 y, which satisfies the axioms Q1....
متن کاملQuandle Coverings and Their Galois Correspondence
This article establishes the algebraic covering theory of quandles. For every connected quandle Q with base point q ∈ Q, we explicitly construct a universal covering p : (Q̃, q̃) → (Q,q). This in turn leads us to define the algebraic fundamental group π1(Q,q) := Aut(p) = {g ∈ Adj(Q)′ | qg = q}, where Adj(Q) is the adjoint group of Q. We then establish the Galois correspondence between connected c...
متن کاملQuandle-like Structures From Groups
We give a general procedure to construct a certain class of ”quandle-like” structures from an arbitrary group. These structures, which we refer to as pseudoquandles, possess two of the three defining properties of quandles. We classify all pseudoquandles obtained from an arbitrary finitely generated abelian group. We also define the notion of the kernel of an element of a pseudoquandle and prov...
متن کاملA polynomial invariant of finite quandles
A quandle is an algebraic structure whose axioms are transcriptions of the three Reidemeister moves, making quandles a natural source of invariants of knots and links. In [8], Joyce associated a finitely generated quandle to each tame knot or link L ⊂ S and proved that this knot quandle determines the knot type up to orientation-reversing homeomorphism of pairs (L, S). Since then, much work has...
متن کاملIndicator of $S$-Hausdorff metric spaces and coupled strong fixed point theorems for pairwise contraction maps
In the study of fixed points of an operator it is useful to consider a more general concept, namely coupled fixed point. Edit In this paper, by using notion partial metric, we introduce a metric space $S$-Hausdorff on the set of all close and bounded subset of $X$. Then the fixed point results of multivalued continuous and surjective mappings are presented. Furthermore, we give a positive resul...
