Let X be a topological space. An n-mean on X is a continuous function ,u: XX which is symmetric and idempotent. In the first part of this paper it is shown that if X is a compact connected abelian… (More)

BackgroundHospital-based Emergency Departments are struggling to provide timely care to a steadily increasing number of unscheduled ED visits. Dwindling compensation and rising ED closures dictate… (More)

A new algorithm is presented for computing the topological entropy of a unimodal map of the interval. The accuracy of the algorithm is discussed and some graphs of the topological entropy which are… (More)

An effective method is given for computing the Hausdorff dimension of the boundary of a self-similar digit tile T in n -dimensional Euclidean space: formula here where 1/c is the contraction factor… (More)

A theoretical approach to computing the Hausdorff dimension of the topological boundary of attractors of iterated function systems is developed. The curve known as the Levy Dragon is then studied in… (More)

Abstract Let f :X→X be a continuous map of a compact metric space to itself. We prove that f is topologically conjugate to an adding machine map if and only if X is an infinite minimal set for f and… (More)

An algorithm is presented for computing the topological entropy of a piecewise monotone map of the interval having three monotone pieces. The accuracy of the algorithm is discussed and some graphs of… (More)

Let X be a proper metric space and let νX be its Higson corona. We prove that the covering dimension of νX does not exceed the asymptotic dimension asdimX of X introduced by M. Gromov. In particular,… (More)

Let E and B be metric continua. Let p:E~>B be a shape fibration in the sense of Mardesic and Rushing. If B is arcwise connected, then all the fibers of p have the same shape. This is also true if B… (More)
