Unknotting 3-spheres in Six Dimensions
Haefliger [2] has shown that a differentiable embedding of the 3-sphere S3 in euclidean 6-dimensions El can be differentiably knotted. On the other hand any piecewise linear embedding of Sn in Ek is combinatorially unknotted if k^n + 3 (see [5; 6; 7]). The case S3 in E6 appears to be the first occasion on which the differentiable and combinatorial theories of isotopy differ. Therefore it seemed...
متن کاملKnots with Unknotting Number 1 and Essential Conway Spheres
For a knot K in S, let T(K) be the characteristic toric sub-orbifold of the orbifold (S, K) as defined by Bonahon-Siebenmann. If K has unknotting number one, we show that an unknotting arc for K can always be found which is disjoint from T(K), unless either K is an EM-knot (of Eudave-Muñoz) or (S,K) contains an EM-tangle after cutting along T(K). As a consequence, we describe exactly which larg...
متن کاملTheories in Five Dimensions
BPS and non-BPS orbits for extremal black-holes in N = 2 MaxwellEinstein supergravity theories (MESGT) in five dimensions were classified long ago by the present authors for the case of symmetric scalar manifolds. Motivated by these results and some recent work on non-supersymmetric attractors we show that attractor equations in N=2 MESGTs in d = 5 do indeed possess the distinct families of sol...
متن کاملSupermultiplets in Five Dimensions
BPS representations of 5-dimensional supersymmetry algebras are classified. For BPS states preserving 1/2 the supersymmetry, there are two distinct classes of multiplets for N = 4 supersymmetry and three classes for N = 8 supersymmetry. For N = 4 matter theories, the two 1/2 supersymmetric BPS multiplets are the massive vector multiplet and the massive self-dual 2-form multiplet. Some applicati...
متن کاملSupergravity in Five Dimensions
We study compactification of five dimensional ungauged N = 2 supergravity coupled to vectorand hypermultiplets on orbifold S/Z2. In the model, the vector multiplets scalar manifold is arbitrary while the hypermultiplet scalars span a generalized self dual Einstein manifold constructed by Calderbank and Pedersen. The bosonic and the fermionic sectors of the low energy effective N = 1 supergravit...
