Technical Report TR - 2004 - 024 Concerning Cut Point Spaces of Order Three
A point p of a topological space X is a cut point of X if X − {p} is disconnected. Further, if X −{p} has precisely m components for some natural number m ≥ 2 we will say that p has cut point order m. If each point y of a connected space Y is a cut point of Y , we will say that Y is a cut point space. Herein we construct a space S so that S is a connected Hausdorff space and each point of S is ...
متن کاملCoincident point and fixed point results for three self mappings in cone metric spaces
In this attempt we proved results on points of coincidence and common xed points for three selfmappings satisfying generalized contractive type conditions in cone metric spaces. Our results gen-eralizes some previous known results in the literature (eg. [5], [6])
متن کاملConcerning the Cut Points of Continua*
In this paper propositions will be established concerning the collection of all the cut points of a given planef continuum. It will be shown that there does not exist an uncountable collection of mutually exclusive subcontinua of a given continuum M each of which contains at least one cut point of M. With the aid of this fundamental theorem it is shown, among other things, that the set of all t...
متن کاملExistence of positive solutions for fourth-order boundary value problems with three- point boundary conditions
In this work, by employing the Krasnosel'skii fixed point theorem, we study the existence of positive solutions of a three-point boundary value problem for the following fourth-order differential equation begin{eqnarray*} left { begin{array}{ll} u^{(4)}(t) -f(t,u(t),u^{prime prime }(t))=0 hspace{1cm} 0 leq t leq 1, & u(0) = u(1)=0, hspace{1cm} alpha u^{prime prime }(0) - beta u^{prime prime pri...
متن کاملOn the Cut Point
We sketch a proof of the fact that the Gromov boundary of a hyperbolic group does not have a global cut point if it is connected. This implies, by a theorem of Bestvina and Mess, that the boundary is locally connected if it is connected. The object of this note is to sketch a proof of the following theorem: Theorem 1. If ? is a one ended hyperbolic group, then the Gromov boundary @? of ? does n...
