WebApr 3, 2024 · A knot is a smooth (or piecewise-linear) embedding of the circle S 1 S^1 into ℝ 3 \mathbb{R}^3, or equivalently into the 3 3-sphere S 3 S^3 (one can also consider knots in other 3-manifolds). Sometimes, higher dimensional knots are also considered. Webknots, links, and 3- and 4-manifolds, developed by Ozsv´ath and Szabo. To a closed 3-manifold Y one associates a graded chain complex dCF(Y) whose chain homotopy type is a powerful homeomorphism invariant of the manifold. A knot K in a 3-manifold Y induces a ﬁltration on the complex dCF(Y), which in turn leads to knot agro gol company

Knots links and 4-manifolds

WebKnot theory is one of the most active research ﬁelds in modern mathematics. Knots and links are closed curves (1-dimensional manifolds) in the Euclidean 3-space, and they are related to braids and 3-manifolds. These notions are generalized into higher dimensions. Surface-knots and surface-links are closed surfaces (2-dimensional WebThe classic paper "The computational complexity of knot and link problems" by Joel Hass, Jeffrey Lagarias, and Nicholas Pippenger [Journal of the ACM 46(2) 185-211 (1999)] established several fundamental complexity results, including showing that determining if a polygonal knot is unknotted is in NP, and that determining the genus of a polygonal knot …

The above example can, in that language, be regarded thus: Consider the 4-manifold obtained by adding a 2-handle to a 4-ball via Kx with framing -1. Add a 2-handle to the trivial knot with framing - 1 (this being a permitted Kirby 'move').
