Some Implications of Semi-1-connectedness1
A topological space X is said to be semi-re-connected at a point xGA" provided there exists an open set U containing x such that every Cech re-cycle on a compact subset of U bounds on X. (If X is regular, "a compact subset of" may be omitted.) If X is semi-re-connected at every point, then X is said to be semi-w-connected [l].2 As shown in [l], if a space has a finite 1-dimensional Betti number...
متن کاملGeodesic Connectedness of Semi-riemannian Manifolds
The problem of geodesic connectedness in semi-Riemannian manifolds (i.e. the question whether each two points of the manifold can be joined by a geodesic) has been widely studied from very different viewpoints. Our purpose is to review these semi-Riemannian techniques, and possible extensions. In the Riemannian case, it is natural to state this problem on (incomplete) manifolds with (possibly n...
متن کاملSome short proofs for connectedness of boundaries
We generalize theorems of Kesten and Deuschel-Pisztora about the connectedness of the exterior boundary of a connected subset of Z, where “connectedness” and “boundary” are understood with respect to various graphs on the vertices of Z. We provide simple and elementary proofs of their results. It turns out that the proper way of viewing these questions is graph theory, instead of topology. Let ...
متن کاملSome remarks on λp,q-connectedness
A connected graph is λp,q-connected if there is a set of edges whose deletion leaves two components of order at least p and q, respectively. In this paper we present some sufficient conditions for graphs to be λp,q-connected. Furthermore, we study λ2,qconnected graphs in more detail.
متن کاملGeneralized semi-pre connectedness in intuitionistic fuzzy topological spaces
In this paper we have introduced the intuitionistic fuzzy generalized semi-pre connected space, intuitionistic fuzzy generalized semipre super connected space and intuitionistic fuzzy generalized semi-pre extremally disconnected space. We investigated some of their properties. Also we characterized the intuitionistic fuzzy generalized semi-pre super connected space. 2010 AMS Classification: 54A...
