چکیده
Given a finitely presented group G and an epimorphism χ : G→ Z, constraints on the orders of automorphisms F : G→ G such that χ ◦ F = χ are obtained via symbolic dynamics. The techniques provide new obstructions to periodicity for knots and links.

متن کاملTORSION NUMBERS OF AUGMENTED GROUPS with applications to knots and links
ABSTRACT. Torsion and Betti numbers for knots are special cases of more general invariants br and βr, respectively, associated to a finitely generated group G and epimorphism χ : G → Z. The sequence of Betti numbers is always periodic; under mild hypotheses about (G,χ), the sequence br satisfies a linear homogeneous recurrence relation with constant coefficients. Generally, br exhibits exponent...

We give an elementary construction of polyhedra whose links are connected bipartite graphs, which are not necessarily isomorphic pairwise. We show, that the fundamental groups of some of our polyhedra contain surface groups. In particular, we construct polyhedra whose links are generalized m-gons. The polyhedra of this type are interesting because of their universal coverings, which are two-dim...

According to a basic prediction made by the Revised Hierarchical Model (RHM), at early stages of language acquisition, strong L2-L1 lexical links are formed. RHM predicts that these links weaken with increasing proficiency, although they do not disappear even at higher levels of language development. To test this prediction, two groups of highly proficie...
متن کاملAn Introduction to Fully Augmented Links
In this article we summarize information on the class of fully augmented links. These links are geometrically explicit, and therefore provide a large class of examples of hyperbolic links for which geometric information can be computed.
