Annular Khovanov homology detects three-strand weaving links

Suman Saurabh

For $N \geq 1$ , let $K_{N}$ be the annular closure of $(σ_{1} σ_{2}^{- 1})^{N} .$ We prove that triply graded annular Khovanov homology over $F_{2}$ detects the underlying unoriented annu…

Equivariant rational sliceness and Klein amphichirality of odd-stranded Turk's head knots

Suman Saurabh

We establish a sharp parity dichotomy for the equivariant $Q$ -sliceness and Klein amphichirality of odd-stranded Turk's head knots. When the twisting parameter $q$ is odd,…

Fox's Trapezoidal Conjecture for Four-Strand Turk's Head Knots and Links

Suman Saurabh

We prove Fox's trapezoidal conjecture for the four-strand Turk's head knots and links $T h (4, q)$ , for all $q \geq 1$ . Equivalently, we show that the absolute values of the coefficien…

Spectral Factorization and Hypergeometric Representations of the Alexander Polynomials of $T h (4, 2 n + 1)$

Suman Saurabh

We study the Alexander polynomials of the 4-strand Turk's head knots $T h (4, 2 n + 1)$ , defined as the closures of the braid $(σ_{1} σ_{2}^{- 1} σ_{3})^{2 n + 1}$ . Using the reduced Burau represent…
