Cowboy bowline Cowboy bowline The cowboy bowline (also left-hand bowline, Dutch marine bowline or winter bowline) is a variation of the bowline loop knot. The cowboy bowline has the working end go around the standing part on the side closer to the loop and results with the working end outside the loop. In contrast, a regular bowline has the working end finishing inside the loop. (The "rabbit" goes around the "tree" in the opposite direction from normal.) Some hearsay suggest the Dutch Navy uses (or used) this variant of the bowline because they consider it superior since the working end is not
Signature of a knot how to compute the "Milnor signature invariants" from this pairing, which are equivalent to the "Tristram-Levine invariant". Signature of a knot The signature of a knot is a topological invariant in knot theory. It may be computed from the Seifert surface. Given a knot "K" in the 3-sphere, it has a Seifert surface "S" whose boundary is "K". The Seifert form of "S" is the pairing formula_1 given by taking the linking number formula_2 where formula_3 and formula_4 indicate the translates of "a" and "b" respectively in the positive and negative directions of the normal bundle to "S".
