چکیده
1. Statement of the main results. It will be convenient for us to define an n-knot to be a smooth, connected, oriented, n-dimensional (closed) submanifold IP of S (oriented). If X" is homeomorphic to S, then we call it a spherical knot. All manifolds in this note will be oriented and all constructions we consider will induce canonical orientations. This will be understood and not commented upon further. Let Kn denote the semigroup of isotopy classes of smooth rc-knots (S, Z). Our object is to define a homomorphism

More 3-manifolds with multiple knot-surgery and branched-cover descriptions
For any integer N ^ 3 we will construct a 3-manifold which can be described as +1 surgery on N distinct knots in S. We will also give examples of 3-manifolds which are i^-fold cyclic branched covers of S over 2 distinct knots. Brakes (2) discovered the first examples of 3-manifolds with multiple knot surgery descriptions. Our construction is much different and follows directly from the construc...
متن کاملHigher Degree Knot Adjacency as Obstruction to Fibering
It is know that the Alexander polynomial detects fibered knots and 3-manifolds that fiber over the circle. In this note, we show that when the Alexander polynomial becomes inconclusive, the notion of “knot adjacency”, studied in [KL], can be used to obtain obstructions to fibering of knots and of 3-manifolds. As an application, given a fibered knot K′, we construct infinitely many non-fibered k...

متن کاملA comparative study of knotting decorations and knot tools Used in Ghaffarieh and Kabud domes of Maragheh city
Knotting is one of the most regular geometric decorations that spread with the spread of Islam. Among the different Islamic governments, the Ilkhani era is one of the most brilliant periods of prosperity and flourishing of art and architecture with the use of knot-making in Iran. Among the magnificent buildings of this period are Kabud Dome and Ghaffarieh Dome, located in Maragheh city, the ext...
متن کاملSeifert Fibred Knot Manifolds
We consider the question of when is the closed manifold obtained by elementary surgery on an n-knot Seifert fibred over a 2-orbifold. After some observations on the classical case, we concentrate on the cases n = 2 and 3. We have found a new family of 2-knots with torsion-free, solvable group, overlooked in earlier work. We show also that there are no aspherical Seifert fibred 3-knot manifolds....
