Connected Components of Spaces of Representations of Non-orientable Surfaces
نویسنده
چکیده
LetM be a compact closed non-orientable surface. We show that the space of representations of the fundamental group of M into PSL(2,R) has exactly two connected components. These two components are the preimages of a certain Stiefel-Whitney characteristic class, computed in a similar way as the Euler class in the orientable case.

Connected Components of Spaces of Surface Group Representations Ii Nan-kuo Ho and Chiu-chu
In [HL1], we discussed the connected components of the space of surface group representations for any compact connected semisimple Lie group and any closed compact (orientable or nonorientable) surface. In this sequel, we generalize the results in [HL1] in two directions: we consider general compact connected Lie groups, and we consider all compact surfaces, including the ones with boundaries. ...
متن کاملOn L-spaces and Left-orderable Fundamental Groups
Examples suggest that there is a correspondence between L-spaces and 3manifolds whose fundamental groups cannot be left-ordered. In this paper we establish the equivalence of these conditions for several large classes of such manifolds. In particular, we prove that they are equivalent for any closed, connected, orientable, geometric 3-manifold that is non-hyperbolic, a family which includes all...
متن کاملOn the connectedness of the branch locus of moduli space of hyperelliptic Klein surfaces with one boundary
2000 Mathematics Suject Classification. Primary 30F10, 30F50; Secondary 14H15, 20H10. Abstract. In this work we prove that the hyperelliptic branch locus of orientable Klein surfaces of genus g with one boundary component is connected and in the case of non-orientable Klein surfaces it has g+1 2 components, if g is odd, and g+2 2 components for even g. We notice that, for non-orientable Klein s...
متن کاملErgodic Action of the Mapping Class Group on Moduli Spaces of Representations of Non-orientable Surfaces
Let M be a non-orientable surface with χ(M) < −1. We consider the moduli space of flat SU(2)-connections, or equivalently the moduli space of representations X (M) = Hom(π1(M), SU(2))/ SU(2). Let ΓM be the mapping class group ofM . There is a natural action of ΓM on X (M) and we show here that this action is ergodic with respect to the natural measure given by the pushforward of Haar measure. T...

Quantisation on spaces with properties of curvature , multiple connectedness and non orientablility is obtained. The geodesic length spectrum for the Laplacian operator is extended to solve the Schroedinger operator. Homotopy fundamental group representations are used to obtain a direct sum of Hilbert spaces, with a Holonomy method for the non simply connected manifolds.The covering spaces of i...
