The Banach algebras and
Ian Doust, Michael Leinert, Alan Stoneham
The spaces and were introduced as part of a program to find a general theory which covers both well-bounded operators and trigonometrically well-bounded operators a…
Convolution dominated operators on compact extensions of abelian groups
Gero Fendler, Michael Leinert
If is a locally compact group, the algebra of convolution dominated operators on then an important question is: Is (respectively if…
On Convolution Dominated Operators
Gero Fendler, Michael Leinert
For a locally compact group we consider the algebra of convolution dominated operators on : An operator is called convolution dominated i…
Wiener's theorem for positive definite functions on hypergroups
Walter R Bloom, John J. F. Fournier, Michael Leinert
The following theorem on the circle group is due to Norbert Wiener: If has non-negative Fourier coefficients and is square integr…
Isomorphisms of spaces
Ian Doust, Michael Leinert
Analogues of the classical Banach-Stone theorem for spaces of continuous functions are studied in the context of the spaces of absolutely continuous functions introduced by Ashton…
Approximation in
Ian Doust, Michael Leinert, Alan Stoneham
For a nonempty compact subset in the plane, the space is the closure of the space of complex polynomials in two real variables under a particular variation norm. In the…
Convolution-Dominated Operators on Discrete Groups
Gero Fendler, Karlheinz Gröchenig, Michael Leinert
We study infinite matrices indexed by a discrete group that are dominated by a convolution operator in the sense that for and some…
