We construct a virtual quandle for links in lens spaces L(p, 1). This invariant has two valuable advantages over an ordinary fundamental quandle for links in lens spaces: the virtual quandle is an essential invariant and the presentation of the virtual quandle can be easily written from the band diagram of a link.

Abstract
We construct a virtual quandle for links in lens spaces L(p, 1). This invariant has two valuable advantages over an ordinary fundamental quandle for links in lens spaces: the virtual quandle is an essential invariant and the presentation of the virtual quandle can be easily written from the band diagram of a link.File in questo prodotto:
