Spherical functions on Euclidean space

open access: yesJournal of Functional Analysis, 2006
We study spherical functions on Euclidean spaces from the viewpoint of Riemannian symmetric spaces. Here the Euclidean space En=G/K where G is the semidirect product Rn⋅K of the translation group with a closed subgroup K of the orthogonal group O(n).

Is Visual Space Euclidean?

Synthese, 1977
Philosophers of past times have claimed that the answer to the question, Is visual space Euclidean?, can be answered by a priori or purely philo­sophical methods. Today such a view is presumably held only in remote philosophical backwaters. It would be generally agreed that one way or another the answer is surely empirical, but the answer might be ...

On characterization of Euclidean spaces

Applied Mathematics and Computation, 2007
Let \(\mathcal{E}\) be a Euclidean plane with Euclidean norm \(\| \dots \| \). A bounded convex centrally symmetric subset \(K\) of \(\mathcal{E}\) with a non-empty interior defines a norm \(\| \dots \| _K\) by \(\| v \| _K = \left(\inf \{r : r v \in K\}\right)^{-1}\).

Embedding of trees in euclidean spaces

Graphs and Combinatorics, 1988
It is proved that for any tree T the vertices of T can be placed on the surface of a sphere in \(R^ 3\) in such a way that adjacent vertices have distance 1 and nonadjacent vertices have distance less than 1. This improves an earlier result of the last three authors (to appear in Discrete and Computational Geometry).

THE EMBEDDING OF COMPACTA IN EUCLIDEAN SPACE

Mathematics of the USSR-Sbornik, 1970
Recently the fundamental importance of the 1-ULC property of the complementary space in describing a given embedding in En has become clear. "Wild" embeddings in En are characterized by the absence of the 1-ULC property. In this paper "tame" and "wild" embeddings in En of arbitrary compacta in codimension at least 3 are defined.

A Representation of Hypergraphs in the Euclidean Space

IEEE Transactions on Computers, 1984
This paper introduces a graph space that shows concisely the relative weights among combinations of vertices of a given hypergraph. (A hypergraph is a graph in which one edge may connect two or more vertices.) The hypergraph is represented by a collection of points in graph space such that the distance between vertices in graph space reflects the ...
