n - QUASI - ISOTOPY : II . COMPARISON
SERGEY A. MELIKHOV and DUŠAN REPOVŠ ABSTRACT We prove that k-quasi-isotopy implies (k + 1)-cobordism of Cochran–Orr, leading to k-quasi-isotopy invariance of Cochran's derived invariants β i , i ≤ k, and Milnor's ¯ µ-invariants of length ≤ 2k + 3. Secondly, k-quasi-isotopic links cannot be distinguished by any Vassiliev invariant of type ≤ k which is well-defined up to PL isotopy, where type ≤ ...
متن کامل5 n - QUASI - ISOTOPY : II . COMPARISON
Geometric aspects of the filtration on classical links by k-quasi-isotopy are discussed, including the effect of Whitehead doubling and relations with Smythe's n-splitting and Kobayashi's k-contractibility. One observation is: ω-quasi-isotopy is equivalent to PL isotopy for links in a homotopy 3-sphere (resp. contractible open 3-manifold) M if and only if M is homeomorphic to S 3 (resp. R 3). A...
متن کاملn-QUASI-ISOTOPY: I. QUESTIONS OF NILPOTENCE
It is well-known that no knot can be cancelled in a connected sum with another knot, whereas every link up to link homotopy can be cancelled in a (componentwise) connected sum with another link. In this paper we address the question whether some form of the ‘complexity accumulation’ property of knots holds for (piecewiselinear) links up to some stronger analogue of link homotopy, which still do...
متن کاملn-QUASI-ISOTOPY: III. ENGEL CONDITIONS
In part I it was shown that for each k ≥ 1 the generalized Sato–Levine invariant detects a gap between k-quasi-isotopy of link and peripheral structure preserving isomorphism of the finest quotient Gk of its fundamental group, ‘functorially’ invariant under k-quasi-isotopy. Here we show that Cochran’s derived invariant β, provided k ≥ 3, and a series of μ̄-invariants, starting with μ̄(111112122) ...
متن کاملTopology during Subdivision of Bézier Curves II: Ambient Isotopy
It is of increasing contemporary interest to preserve ambient isotopy during geometric modeling. Bézier curves are pervasive in computer aided geometric design, as one of the fundamental computational representations for geometric modeling. For Bézier curves, subdivision algorithms create control polygons as piecewise linear (PL) approximations that converge under Hausdorff distance. A natural ...
