Tangled Tangles

چکیده
The Tangle toy [Zaw15, Zaw85] is a topological manipulation toy that can be twisted and turned in a variety of different ways, producing different geometric configurations. Some of these configurations lie in 3D space while others may be flattened into planar shapes. The toy consists of several curved, quarter-circle pieces fit together at rotational/twist joints. Each quarter-circle piece can be rotated about either of the two joints that connect it to its two neighboring pieces. Fig. 1 shows a couple of Tangle toys that can be physically twisted into many 3D configurations. See [Zaw15] for more information and demonstrations of the toy.

Tangled up in Blue (A Survey on Connectivity, Decompositions, and Tangles)
We survey an abstract theory of connectivity, based on symmetric submodular set functions. We start by developing Robertson and Seymour’s [44] fundamental duality theory between branch decompositions (related to the better-known tree decompositions) and so-called tangles, which may be viewed as highly connected regions in a connectivity system. We move on to studying canonical decompositions of...
متن کاملSmall-scale microwave background anisotropies due to tangled primordial magnetic fields
An inhomogeneous cosmological magnetic field creates vortical perturbations that survive Silk damping on much smaller scales than compressional modes. This ensures that there is no sharp cut-off in anisotropy on arc-minute scales. As we had pointed out earlier, tangled magnetic fields, if they exist, will then be a potentially important contributor to small-angular scale CMBR anisotropies. Seve...
متن کاملTangled Splines
Extracting shape information from object boundaries is a well studied problem in vision, and has found tremendous use in applications like object recognition. Conversely, studying the space of shapes represented by curves satisfying certain constraints is also intriguing. In this paper, we model and analyze the space of shapes represented by a 3D curve (space curve) formed by connecting n piece...
متن کاملSmall-scale CMB polarization anisotropies due to tangled primordial magnetic fields
Tangled, primordial cosmic magnetic fields create small rotational velocity perturbations on the last scattering surface (LSS) of the cosmic microwave background radiation (CMBR). Such perturbations can contribute significantly to the CMBR temperature and polarization anisotropies at large l > 1000 or so, like the excess power detected by the CBI experiment. The magnetic contribution can be dis...
متن کاملVortex knots in tangled quantum eigenfunctions
Tangles of string typically become knotted, from macroscopic twine down to long-chain macromolecules such as DNA. Here, we demonstrate that knotting also occurs in quantum wavefunctions, where the tangled filaments are vortices (nodal lines/phase singularities). The probability that a vortex loop is knotted is found to increase with its length, and a wide gamut of knots from standard tabulation...
متن کاملTangled DNA tightens chromosomes
Tangled DNA tightens chromosomes C ramming your vacation wardrobe into your luggage is a breeze compared with the packing job cells perform. Before they can divide, they have to scrunch long DNA molecules into tiny chromosomes. The tangles that form in DNA molecules help this chromosome compression, Kawamura et al. report. The team studies newt chromosomes—they are large and convenient to obser...
