Knot cobordism and Lee's Perturbation of Khovanov homology [PDF]

open access: yesJournal of knot theory and its ramifications, 2022
For a connected cobordism S between two knots K1,K2 in S , we establish an inequality involving the number of local maxima, the genus of S, and the torsion orders of Kht(K1),Kht(K2), where Kht denotes Lee’s perturbation of Khovanov homology.

An introduction to Thompson knot theory and to Jones subgroups [PDF]

open access: yesJournal of knot theory and its ramifications, 2022
We review a constructions of knots from elements of the Thompson groups due to Vaughan Jones, which comes in two flavours: oriented and unoriented.

A Transfer Residual Neural Network Based on ResNet-34 for Detection of Wood Knot Defects

open access: yesForests, 2021
In recent years, due to the shortage of timber resources, it has become necessary to reduce the excessive consumption of forest resources. Non-destructive testing technology can quickly find wood defects and effectively improve wood utilization.

A two-variable series for knot complements [PDF]

open access: yesQuantum Topology, 2019
The physical 3d $\mathcal{N}=2$ theory T[Y] was previously used to predict the existence of some 3-manifold invariants $\hat{Z}_{a}(q)$ that take the form of power series with integer coefficients, converging in the unit disk.

Industrial Application of Nanocelluloses in Papermaking: A Review of Challenges, Technical Solutions, and Market Perspectives

open access: yesMolecules, 2020
Nanocelluloses (NC) increase mechanical and barrier paper properties allowing the use of paper in applications actually covered by other materials. Despite the exponential increase of information, NC have not been fully implemented in papermaking yet ...

Large color R-matrix for knot complements and strange identities [PDF]

open access: yesJournal of knot theory and its ramifications, 2020
The Gukov–Manolescu series, denoted by [Formula: see text], is a conjectural invariant of knot complements that, in a sense, analytically continues the colored Jones polynomials.

A lower bound on the average genus of a 2-bridge knot [PDF]

open access: yesJournal of knot theory and its ramifications, 2021
Experimental data from Dunfield et al using random grid diagrams suggests that the genus of a knot grows linearly with respect to the crossing number. Using billiard table diagrams of Chebyshev knots developed by Koseleff and Pecker and a random model of

Tidal surface states as fingerprints of non-Hermitian nodal knot metals [PDF]

open access: yesCommunications Physics, 2018
Non-Hermitian nodal knot metals (NKMs) contain intricate complex-valued energy bands which give rise to knotted exceptional loops and new topological surface states. We introduce a formalism that connects the algebraic, geometric, and topological aspects
