Symmetries of Spatial Graphs and Rational Twists along Spheres and Tori
نویسنده
چکیده
A symmetry group of a spatial graph Γ in S is a finite group consisting of orientation-preserving self-diffeomorphisms of S which leave Γ setwise invariant. In this paper, we show that in many cases symmetry groups of Γ which agree on a regular neighborhood of Γ are equivalent up to conjugate by rational twists along incompressible spheres and tori in the exterior of Γ .

Perturbed Floer Homology of Some Fibered Three Manifolds Ii
Modifying the method of [21], we compute the perturbed HF for some special classes of fibered three manifolds in the second highest spin-structures Sg−2. The special classes considered in this paper include the mapping tori of Dehn twists along a single non-separating curve and along a transverse pair of curves.
متن کاملOmega Polynomial in Polybenzene Multi Tori
The polybenzene units BTX 48, X=A (armchair) and X=Z (zig-zag) dimerize forming “eclipsed” isomers, the oligomers of which form structures of five-fold symmetry, called multi-tori. Multi-tori can be designed by appropriate map operations. The genus of multi-tori was calculated from the number of tetrapodal units they consist. A description, in terms of Omega polynomial, of the two linearly peri...
متن کاملPartial Approximate Symmetry Detection of Geometric Model
Engineering geometric models are often designed to have symmetries and other regularities. In knowledge based reuse, creative design and design for mass customization, to have the information of such symmetries and other regularities from a geometric model is very useful. And this can make us understand more about the geometric model. In reverse engineering, B-rep models are created by fitting ...
متن کاملFukaya Algebras and the Minimal Model Program
We prove that small blow-ups or reverse flips (in the sense of the minimal model program) of rational symplectic manifolds with point centers create Floer-non-trivial Lagrangian tori. We give examples of explicit mmp runnings and descriptions of Floer non-trivial tori in the case of toric manifolds, polygon spaces, and moduli spaces of flat bundles on punctured two-spheres (moduli of parabolic ...
متن کاملDALD:-Distributed-Asynchronous-Local-Decontamination Algorithm in Arbitrary Graphs
Network environments always can be invaded by intruder agents. In networks where nodes are performing some computations, intruder agents might contaminate some nodes. Therefore, problem of decontaminating a network infected by intruder agents is one of the major problems in these networks. In this paper, we present a distributed asynchronous local algorithm for decontaminating a network. In mos...
