On invariants of multiplexed virtual links

Kodai Wada

For a virtual knot $K$ and an integer $r$ with $r \geq 2$ , we introduce a method of constructing an $r$ -component virtual link $L (K; r)$ , which we call the $r$ -multiplexing of $K$ . Ev…

Writhes and $2 k$ -moves for virtual knots

Kodai Wada

A $2 k$ -move is a local deformation adding or removing $2 k$ half-twists. We show that if two virtual knots are related by a finite sequence of $2 k$ -moves, then their $n$ -writhes are…
