Obstructions to shake sliceness for links
نویسندگان
چکیده
Shake slice generalizes the notion of a link, naturally extending shake knots to links. There is also relative version, concordance, that link concordance. We show if two links are concordant, then their zero surgery manifolds homology cobordant. Then we give several obstructions being slice; for instance, Arf invariants vanish both and each component. Finally bounds disjoint disks in 4-ball hence component algebraically slice.

Eta Invariants as Sliceness Obstructions and Their Relation to Casson-gordon Invariants
We give a useful classification of the metabelian unitary representations of π1(MK), where MK is the result of zero-surgery along a knot K ⊂ S . We show that certain eta invariants associated to metabelian representations π1(MK)→ U(k) vanish for slice knots and that even more eta invariants vanish for ribbon knots and doubly slice knots. We show that our vanishing results contain the Casson–Gor...
متن کاملSome Examples Related to Knot Sliceness
It is known that the linking form on the 2-cover of slice knots has a metabolizer. We show that several weaker conditions, or some other conditions related to sliceness, do not imply the existence of a metabolizer. We then show how the Rudolph-Bennequin inequality can be used indirectly to prove that some knots are not slice.
متن کاملQuasipositivity as an Obstruction to Sliceness
For an oriented link L C S3 = dD4 , let Xs(L) be the greatest Euler characteristic x(F) of an oriented 2-manifold F (without closed components) smoothly embedded in D4 with boundary L . A knot K is slice if Xs(K) = 1 . Realize D4 in C2 as {(z, w) : \z\2 + \w\2 < 1} . It has been conjectured that, if V is a nonsingular complex plane curve transverse to S3 , then Xs(VnS3) = ^(KnZ)4).

متن کاملObstructions to Shiftedness
In this paper we show results on the combinatorial properties of shifted simplicial complexes. We prove two intrinsic characterization theorems for this class. The first theorem is in terms of a generalized vicinal preorder. It is shown that a complex is shifted if and only if the preorder is total. Building on this we characterize obstructions to shiftedness and prove there are finitely many i...
متن کاملShake-Shake regularization
The method introduced in this paper aims at helping deep learning practitioners faced with an overfit problem. The idea is to replace, in a multi-branch network, the standard summation of parallel branches with a stochastic affine combination. Applied to 3-branch residual networks, shake-shake regularization improves on the best single shot published results on CIFAR-10 and CIFAR100 by reaching...
