Self Delta-equivalence for Links Whose Milnor’s Isotopy Invariants Vanish
For an n-component link, Milnor’s isotopy invariants are defined for each multi-index I = i1i2...im (ij ∈ {1, ..., n}). Here m is called the length. Let r(I) denote the maximum number of times that any index appears in I. It is known that Milnor invariants with r = 1, i.e., Milnor invariants for all multi-indices I with r(I) = 1, are link-homotopy invariant. N. Habegger and X. S. Lin showed tha...
متن کاملMilnor ’ S Isotopy Invariants and Generalized Link
It has long been known that a Milnor invariant with no repeated index is an invariant of link homotopy. We show that Milnor’s invariants with repeated indices are invariants not only of isotopy, but also of self Ck-moves. A self Ck-move is a natural generalization of link homotopy based on certain degree k clasper surgeries, which provides a filtration of link homotopy classes.
متن کاملFinite Type Invariants and Milnor Invariants for Brunnian Links
A link L in the 3-sphere is called Brunnian if every proper sublink of L is trivial. In a previous paper, the first author proved that the restriction to Brunnian links of any Goussarov-Vassiliev finite type invariant of (n + 1)component links of degree < 2n is trivial. The purpose of this paper is to study the first nontrivial case. We show that the restriction of an invariant of degree 2n to ...
متن کاملThe Khovanov’s Invariants for Alternating Links
In this paper, we prove the first conjecture of Bar-Natan, Garo-ufalidis, and Khovanov's on the Khovanov's invariants for alternating knots. 1. The map Φ The first conjecture states that there is an almost pairing of the cohomology groups of degree difference (1,4), so it is natural to think of a map of degree (1,4) on the cohomology groups. On chain level, the map Φ is defined in the same fash...
متن کاملAnalytic Invariants of Boundary Links
Using basic topology and linear algebra, we define a plethora of invariants of boundary links whose values are power series with noncommuting variables. These turn out to be useful and elementary reformulations of an invariant originally defined by M. Farber [Fa2].
