Boring Split Links
Boring is an operation which converts a knot or two-component link in a 3–manifold into another knot or two-component link. It generalizes rational tangle replacement and can be described as a type of 2–handle attachment. Sutured manifold theory is used to study the existence of essential spheres and planar surfaces in the exteriors of knots and links obtained by boring a split link. It is show...
متن کاملBoring Split Links and Unknots
Boring is an operation which converts a knot or two-component link in a 3–manifold into another knot or two-component link. It generalizes rational tangle replacement and can be described as a type of 2–handle attachment. Sutured manifold theory is used to find lower bounds for the genus of knots obtained by boring split links and unknots. Bounds on the euler characteristic of essential planar ...
متن کاملIntegrality of the Averaged Jones Polynomial of Algebraically Split Links
n!φn(L) ∈ 6Z. This conjecture is verified for n = 1, 2 in [LW], and we consider the case n ≥ 3 here. We first establish that an(L) ∈ Z whenever L is a geometrically split link (GSL), implying that φn(L) ∈ 2Z, which is a priori stronger than the conjecture in this case. Nevertheless, Conjecture 4.1 is not true for ASLs. The problem is the presence of additional factors of 2 in the denominator of...
متن کاملCross-layer enhancement of TCP split-connections over satellites links
Satellites have played an important role in global telecommunications. However, transmission control protocol (TCP) suffers performance degradations over satellite links due to the long propagation delay and high bit-error rate. Among methods proposed to alleviate the impact of satellite link characteristics on TCP performance, split TCP connections separated by performance enhancement proxies ...
متن کامل0 Split - step solitons in long fiber links
We consider a long fiber-optical link consisting of alternating dispersive and nonlinear segments, i.e., a split-step model (SSM), in which the dispersion and nonlinearity are completely separated. Passage of a soliton (localized pulse) through one cell of the link is described by an analytically derived map. Multiple numerical iterations of the map reveal that, at values of the system’s stepsi...
