The non-semi-simple term in the trace formula for rank one lattices.
For we calculate the norm of the Fourier transform from the space on a finite abelian group to the space on the dual group.
Let A be a commutative Banach algebra and let be its structure space. The norm spectrum σ(f) of the functional f ∈ A* is defined by , where f·a is the functional on A defined by ⟨f·a,b⟩ = ⟨f,ab⟩, b ∈ A. We investigate basic properties of the norm spectrum in certain classes of commutative Banach algebras and present some applications.
Let be a locally compact group, and let be a function norm on such that the space of all locally integrable functions with finite -norm is an invariant solid Banach function space. Consider the space of all functions in of which the right translation is a continuous map from into . Characterizations of the case where is a Riesz ideal of are given in terms of the order-continuity of on certain subspaces of . Throughout the paper, the discussion is carried out in the context...
We prove that in order to describe the Poisson boundary of rational affinities, it is necessary and sufficient to consider the action on real and all -adic fileds.
A number of recent papers have been devoted to the study of prevalence, a generalization of the property of being of full Haar measure to topological groups which need not have a Haar measure, and the dual concept of shyness. These concepts give a notion of "largeness" which often differs from the category analogue, comeagerness, and may be closer to the intuitive notion of "almost everywhere." In this paper, we consider the group of permutations of natural numbers. Here, in the sense of category,...
