WebWe develop obstructions to a knot bounding a smooth punctured Klein bottle in . The simplest of these is based on the linking form of the 2–fold branched cover of branched … Like the Möbius strip, the Klein bottle is a two-dimensional manifold which is not orientable. Unlike the Möbius strip, it is a closed manifold, meaning it is a compact manifold without boundary. While the Möbius strip can be embedded in three-dimensional Euclidean space R , the Klein bottle cannot. It can be embedded in R , however. bindoon sub clover
