A link polynomial via wall crossings
Given an oriented link L in 3-space we consider a generic homotopy connecting L with the unlink. To each singular link in the homotopy we associate some polynomial using an extension of the Kauffman bracket. The signed sum of these polynomials is a new link invariant, called Cross(L). It is determined by the following skein relations: Cross(unlink) = 0 Cross(L+)− Cross(L−) = t −1/2V (L+) + t 1/...
متن کاملIntrinsic Symmetry Groups of Links with 8 and Fewer Crossings
We present new computations of “intrinsic” symmetry groups for knots and links of 8 or fewer crossings. The standard symmetry group for a link is the mapping class group MCG(S, L) or Sym(L) of the pair (S, L). Elements in this symmetry group can (and often do) fix the link and act nontrivially only on its complement. We ignore such elements and focus on the “intrinsic” symmetry group of a link,...
متن کاملWall-crossings in Toric Gromov–witten Theory Ii: Local Examples
In this paper we analyze six examples of birational transformations between toric orbifolds: three crepant resolutions, two crepant partial resolutions, and a flop. We study the effect of these transformations on genus-zero Gromov–Witten invariants, proving the Coates–Corti–Iritani–Tseng/Ruan form of the Crepant Resolution Conjecture in each case. Our results suggest that this form of the Crepa...
متن کاملWall-crossings in Toric Gromov–witten Theory I: Crepant Examples
The Crepant Resolution Conjecture of Ruan and Bryan–Graber asserts that certain generating functions for genus-zero Gromov–Witten invariants of an orbifold X can be obtained from their counterparts for a crepant resolution of X by analytic continuation followed by specialization of parameters. In this paper we use mirror symmetry to determine the relationship between the genus-zero Gromov–Witte...
متن کاملIntrinsic domain-wall resistance in ferromagnetic semiconductors.
Transport through zinc blende magnetic semiconductors with magnetic domain walls is studied theoretically. We show that these magnetic domain walls have an intrinsic resistance due to the effective hole spin-orbit interaction. The intrinsic resistance is independent of the domain-wall shape and width and survives the adiabatic limit. For typical parameters, the intrinsic domain-wall resistance ...
