This paper shows all elements in the 3-colorable subgroup of Thompson's group give 3-colorable links.

problem Exploring the relationship between elements in the 3-colorable subgroup of Thompson's group and 3-colorable links.

This paper has two-fold goal: it provides gentle introduction to Knot Theory starting from 3-coloring, the concept introduced by R. Fox to allow undergraduate students to see that the trefoil knot is non-trivial, and ending with statistical mechanics. On the way we prove various (old and new) facts about knots. We rela…

The colored Jones polynomial is a qq-polynomial invariant of links colored by irreducible representations of a simple Lie algebra. A qq-series called a tail is obtained as the limit of the sl2\mathfrak{sl}_2 colored Jones polynomials {Jn(K;q)}n\{J_n(K;q)\}_n for some link KK, for example, an alternating link. For the $\mathf…

Rosso and Jones gave a formula for the colored Jones polynomial of a torus knot, colored by an irreducible representation of a simple Lie algebra. The Rosso-Jones formula involves a plethysm function, unknown in general. We provide an explicit formula for the second plethysm of an arbitrary representation of $\fsl_3$, …

This paper is base on talks which I gave in May, 2010 at Workshop in Trieste (ICTP). In the first part we present an introduction to knots and knot theory from an historical perspective, starting from Summerian knots and ending on Fox 3-coloring. We show also a relation between 3-colorings and the Jones polynomial. In …

This paper is a next step in the project of systematic description of colored knot polynomials started in arXiv:1506.00339. In this paper, we managed to explicitly find the inclusive\textit{inclusive} Racah matrices, i.e. the whole set of mixing matrices in channels R3QR^{\otimes 3}\longrightarrow Q with all possible QQ, for …

The Kauffman-Vogel polynomials are three variable polynomial invariants of 44-valent rigid vertex graphs. A one-variable specialization of the Kauffman-Vogel polynomials for unoriented 44-valent rigid vertex graphs was given by using the Kauffman bracket and the Jones-Wenzl idempotent colored with 22. Bataineh, Elha…

A small cover was introduced by Davis and Januszkiewicz as an nn-dimensional closed manifold with a locally standard Z2)nZ_2)^n-action such that its orbit space is a simple convex polytope. There exist a one-to-one correspondence between small covers and (Z2)n(Z_2)^n-colored polytopes. In this paper we study a construction…

Let KS3K\subset S^3 be a Fox pp-colored knot and assume KK bounds a locally flat surface SB4S\subset B^4 over which the given pp-coloring extends. This coloring of SS induces a dihedral branched cover XS4X\to S^4. Its branching set is a closed surface embedded in S4S^4 locally flatly away from one singularity whose li…

We present updates to the problems on Hirzebruch's 1954 problem list focussing on open problems, and on those where substantial progress has been made in recent years. We discuss some purely topological problems, as well as geometric problems about (almost) complex structures, both algebraic and non-algebraic, about co…
