A point p in a dendroid X is a shore point if there exists a sequence of subdendroids of X not containing p and converging to X with respect to the Hausdorff metric. The purpose of this paper is to present new results relating shore points and noncut

We give a proof of a graph-theoretical Jordan curve theorem which generalizes both the topological results of Khalimsky et al. as well as some of the graph-theoretical results of Rosenfeld and Klette and Voss.

We obtain sufficient conditions for a linearly ordered topological space (LOTS) to be densely orderable. As a consequence we obtain a characterization of those metrizable LOTS with connected ordered compactifications.

A continuum is 1 2 -homogeneous provided there are exactly two orbits for the action of the group of homeomorphisms of the continuum onto itself. In this paper we study some relations between 1 2 -homogeneous continua and their set of cut points. We
