On representation varieties of 3–manifold groups

چکیده
are affine algebraic schemes over Q. Our goal is to show that, to some extent, these are the only restrictions on local geometry of the representation and character schemes of fundamental groups of closed 3–manifolds. The universality theorem we thus obtain is one of many universality theorems about moduli spaces of geometric objects; see Mnëv [11], Richter-Gebert [15], Kapovich and Millson [6; 7; 8], Vakil [18], Payne [13], Rapinchuk [14].

In this paper, a sparse representation based manifold learning method is proposed. The construction of the graph manifold in high dimensional space is the most important step of the manifold learning methods that is divided into local and gobal groups. The proposed graph manifold extracts local and global features, simultanstly. After construction the sparse representation based graph manifold,...
متن کاملComputing Varieties of Representations of Hyperbolic 3-Manifolds into SL(4, ℝ)
Following the seminal work of M. Culler and P. Shalen [Culler & Shalen, 1983], and that of A. Casson [Akbulut & McCarthy, 1990], the theory of representation and character varieties of 3-manifolds has come to be recognized as a powerful tool, and has duly assumed an important place in low-dimensional topology. Among the many papers that have appeared in this context, we mention [Culler et al., ...
متن کاملGauge Theory Invariants, and Surgery on Knots
Paul Kirk* ABSTRACT: Chern-Simons and spectral flow invariants of representations of 3-manifold groups are investigated in the context of Dehn surgery on knots. Various formulae and computational methods are explained, and examples are worked out. The guiding principle is that information about these invariants can be obtained entirely from the representation varieties of the manifolds, i.e. wi...
متن کاملGeometric Structures and Varieties of Representations
Many interesting geometric structures on manifolds can be interpreted as structures locally modelled on homogeneous spaces. Given a homogeneous space (X,G) and a manifold M , there is a deformation space of structures on M locally modelled on the geometry of X invariant under G. Such a geometric structure on a manifold M determines a representation (unique up to inner automorphism) of the funda...
متن کاملSymplectic Topology of Su(2)-representation Varieties and Link Homology, I: Symplectic Braid Action and the First Chern Class
There are some similarities between cohomology of SU(2)-representation varieties of the fundamental group of some link complements and the Khovanov homology of the links. We start here a program to explain a possible source of these similarities. We introduce a symplectic manifold M with an action of the braid group B2n preserving the symplectic structure. The action allows to associate a Lagra...
