Equivariant Nielsen Invariants for Discrete Groups
For discrete groups G, we introduce equivariant Nielsen invariants. They are equivariant analogs of the Nielsen number and give lower bounds for the number of fixed point orbits in the G-homotopy class of an equivariant endomorphism f : X → X. Under mild hypotheses, these lower bounds are sharp. We use the equivariant Nielsen invariants to show that a G-equivariant endomorphism f is G-homotopic...
متن کاملTwisted Equivariant K-theory for Proper actions of Discrete Groups
We will make a construction of twisted equivairant K-theory for proper actions of discrete groups by using ideas of Lück and Oliver [16] to expand a construction of Adem and Ruan [1].
متن کاملEquivariant -invariants and -forms
Let a Lie group G act isometrically on an odd dimensional Riemannian manifold M and let D be a G-equivariant operator of Dirac type on M. We construct a formal power series X (D) in X 2 g, which can be interpreted as a universal-form for families of Dirac operators induced by D over brations with bres isometric to M and with structure group G. For a Killing eld X 2 g without zeroes, rX (D) is t...
متن کاملEquivariant - Invariants on Homogeneous Spaces
Let D be a homogeneous Dirac operator on the quotient M = G=H of two compact connected Lie groups. We construct a deformation ~ D of D and calculate its equivariant-invariant G (~ D) explicitly on the dense subset G 0 of G that acts freely on M. On G 0 , G (~ D) and G (D) diier only by a virtual character of G.
متن کاملEquivariant covers for hyperbolic groups
Recall that a cover U is of dimension N if every x 2 X is contained in no more then N C 1 members of U . The asymptotic dimension of a finitely generated group is its asymptotic dimension as a metric space with respect to any word metric. An important result of Yu [19] asserts that the Novikov conjecture holds for groups of finite asymptotic dimension. This can be viewed as an injectivity resul...
