摘要：
Several authors have recently studied virtual knots and links because they admit invariants arising from R-matrices. We prove that every virtual link is uniquely represented by a link L subset of S x I in a thickened, compact, oriented surface S such that the link complement (S x I) \ L has no essential vertical cylinder.
