On the Invariant Uniform Roe Algebra as Crossed Product
The uniform Roe C U G . The reduced C algebra C G is naturally contained in CU G . We show that the elements of l∞ which are invariant under are of the form l∞ . Finally we show that if and are bounded geometry discrete metric spaces, then
متن کاملInvariant elements in the dual Steenrod algebra
In this paper, we investigate the invariant elements of the dual mod $p$ Steenrod subalgebra ${mathcal{A}_p}^*$ under the conjugation map $chi$ and give bounds on the dimensions of $(chi-1)({mathcal{A}_p}^*)_d$, where $({mathcal{A}_p}^*)_d$ is the dimension of ${mathcal{A}_p}^*$ in degree $d$.
متن کاملFinite Codimensional Invariant Subspace and Uniform Algebra
Finite codimensional invariant subspaces in the abstract Hardy space defined by a unique representing measure on a uniform algebra are described. Mathematics Subject Classification: Primary 47B48
متن کاملK-theory for the Maximal Roe Algebra of Certain Expanders
We study in this paper the maximal version of the coarse BaumConnes assembly map for families of expanding graphs arising from residually finite groups. Unlike for the usual Roe algebra, we show that this assembly map is closely related to the (maximal) Baum-Connes assembly map for the group and is an isomorphism for a class of expanders. We also introduce a quantitative Baum-Connes assembly ma...
متن کاملOn uniform spaces with invariant nonstandard hulls
Let 〈X,Γ〉 be a uniform space with its uniformity generated by a set of pseudo-metrics Γ . Let the symbol “ ' " denote the usual infinitesimal relation on ∗X , and define a new infinitesimal relation “ ≈ " by writing x ≈ y whenever ∗ρ(x, p) ' ∗ρ(y, p) for each ρ ∈ Γ and each p ∈ X . Let us call a uniform space 〈X,Γ〉 an S-space if the relations ' and ≈ coincide on fin(∗X). In [14], we showed that...
