Diagrams realizing prescribed sublink diagrams for virtual links and welded links

Abstract

Jin and Lee proved the following: Suppose that $D_1,\dots ,D_n$ are link diagrams. Given a link $L$ which is partitioned into sublinks $L_1,\dots ,L_n$ admitting diagrams $D_1,\dots ,D_n$ respectively, there is a diagram $D$ of $L$ whose restrictions to $L_1,\dots ,L_n$ are isotopic to $D_1,\dots ,D_n$, respectively. In this paper we show that a similar result does hold for welded links and does not for virtual links.
