Convolution dominated operators on compact extensions of abelian groups

Gero Fendler, Michael Leinert

If $G$ is a locally compact group, $C D (G)$ the algebra of convolution dominated operators on $L^{2} (G)$ then an important question is: Is $C 1 + C D (G)$ (respectively $C D (G)$ if…

On Convolution Dominated Operators

Gero Fendler, Michael Leinert

For a locally compact group $G$ we consider the algebra $C D (G)$ of convolution dominated operators on $L^{2} (G)$ : An operator $A : L^{2} (G) \to L^{2} (G)$ is called convolution dominated i…

Separable $C^{}$ -Algebras and weak $^{}$ -fixed point property

Gero Fendler, Michael Leinert

It is shown that the dual $A^$ of a separable $C^{*}$ -algebra $A$ is discrete if and only if its Banach space dual has the weak $^{*}$ -fixed point property. We prove furt…

Relatively compact sets in the reduced $C^{*}$ -algebras of Coxeter groups

Gero Fendler

We characterize relatively norm compact sets in the regular $C^{*}$ -algebra of finitely generated Coxeter groups using a geometrically defined positive semigroup acting on the algebr…

N Dilations and Transference for Continuous One-Parameter Semigroups of Positive Contractions on $L^{p}$ -spaces

Gero Fendler

These are the notes of a lecture given at the university of Wroclaw in 1996. We present results of semigroups of (sub)positive contractions on L^p-spaces. The dilation theorem of A…

Convolution-Dominated Operators on Discrete Groups

Gero Fendler, Karlheinz Gröchenig, Michael Leinert

We study infinite matrices $A$ indexed by a discrete group $G$ that are dominated by a convolution operator in the sense that $∣ (A c) (x) ∣ \leq (a * ∣ c ∣) (x)$ for $x \in G$ and some…
