A metric space (X, D) is called circular if it is isometric to a subspace of a metric circle, that is, a circle in which distances are measured by the length of the shorter arc connecting them. We show that the following three conditions are equivale

Fuzzy rings are, on the one handside, an appropriate tool for a unified approach to representable, oriented, and valuated matroids. On the other hand, they also serve to unify the relatively new field of “Tropical Geometry” and “Classical Algeb

In this paper, it is argued that the fact that, so far, even the worst and most far-reaching epidemics-from the Plague of Athens in 430 BC and the Plague of Justinian in 541/542 AD to the Hong Kong Flu from 1968/69-always finally petered out can be e

To any metric D on a finite set X, one can associate a metric space T(D) known as its tight span. Properties of T(D) often reveal salient properties of D. For example, cut sets of T(D), i.e., subsets of T(D) whose removal disconnect T(D), can help to

In this paper, we present an analysis of oracle bone characters for animals from a “cognitive” point of view. After some general remarks on oracle-bone characters presented in Sec. 1 and a short outline of the paper in Sec. 2, we collect various

In this paper, we analyze a rather simple system in which some substance is being stored, released, and replenished simultaneously in some interdependent way. We investigate the dynamic behavior of such a system, using a two-dimensional map-based dis

The relatively new field of “Tropical Geometry” and “Classical Algebraic Geometry” have much in common. In this paper, we present a unified approach to both of these fields by studying more general “Fuzzy Geometries” over fuzzy rings. It

For F a p-adic field together with a p-adic valuation, we present a new characterization for a map p: F-n -> R boolean OR {-infinity} to be a delta-adic norm on the vector space F-n. This characterization was motivated by the concept of tight maps-ma

We present a technique to find threshold values that allows the user to separate signal from noise in fluorescence grey-level images. It can be classified as a purely comparative method based upon the amount of “Mutual Information” between two or

We introduce the concept of single-linkage equivalence of edge-weighted graphs, we apply it to characterise maximal spanning trees and “ultra-similarities”, and we discuss how it relates to the popular single-linkage clustering algorithm.
