Covering Link Calculus and Iterated Bing Doubles
We give a new geometric obstruction to the iterated Bing double of a knot being a slice link: for n > 1 the (n + 1)st iterated Bing double of a knot is rationally slice if and only if the nth iterated Bing double of the knot is rationally slice. The main technique of the proof is a covering link construction simplifying a given link. We prove certain similar geometric obstructions for n ≤ 1 as ...
متن کاملAlgebraic and Heegaard-floer Invariants of Knots with Slice Bing Doubles
If the Bing double of a knot K is slice, then K is algebraically slice. In addition the Heegaard–Floer concordance invariants τ , developed by Ozsváth-Szabó, and δ, developed by Manolescu and Owens, vanish on K. For a knot K ⊂ S, the Bing double, denoted B(K), is the two component link illustrated schematically in Figure 1. Within the box the two strands run parallel along a diagram for K, and ...
متن کاملQuantization of Drinfel’d doubles
Hopf algebra quantizations of 4-dimensional and 6-dimensional real classical Drinfel’d doubles are studied by following a direct “analytic” approach. The full quantization is explicitly obtained for most of the Drinfel’d doubles, except a small number of them for which the dual Lie algebra is either sl2 or so(3). In the latter cases, the classical r-matrices underlying the Drinfel’d double quan...
متن کاملCracking BING and Beyond
The problem, generic objectness proposal, aims to reduce the candidate windows for object detection tasks. The popular evaluation criterion for related methods is detection-rate/windows-amount(DR-#WIN), where DR is the percentage of groundtruth objects covered by proposal windows. An object is considered “covered” by a window only if the strict PASCAL-overall criterion [3] is satisfied (the int...
متن کاملQuotients of Bing Spaces
A Bing space is a compact Hausdorff space whose every component is a hereditarily indecomposable continuum. We investigate spaces which are quotients of a Bing space by means of a map which is injective on components. We show that the class of such spaces does not include every compact space, but does properly include the class of compact metric spaces. Our entire development is based on Krasin...
