We give necessary and sufficient conditions for the existence of a continuous extension from a smallest-neighborhood space (Alexandrov space) X to the Khalimsky line. Using this result, we classify the subsets A ⊂ X such that every continuous function A → Z can be extended to all of X. We also consider the more general case of mappings X → Y between smallest-neighborhood spaces, and prove a dig...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
Can network technology stimulate communities of propinquity and sustainability? We explore in this study the relation between communication technology, the production of space for public life, and community building in the contemporary city. For that we propose the collaboration of urban planning and computer science, for the design of virtual communities that are deferent to physical space (hy...
Men who have sex with men (MSM) accounted for 61% of new HIV diagnoses in the United States in 2010. Recent analyses indicate that socio-structural factors are important correlates of HIV infection. NYCM2M was a cross-sectional study designed to identify neighborhood-level characteristics within the urban environment that influence sexual risk behaviors, substance use and depression among MSM l...
Currently, old textures are one of the main problems in many cities and even villages in our country. The specific feature of these textures makes it necessary to be considered from different aspects. This study is trying to find strategies to improve and organize old texture in the Shahidgah neighborhood of Ardabil. It also aims to plan and design in accordance with the existing status and con...
Introduction: Cultural diversity, ethnicity, differences in language, and different living crimes are among the most enduring challenges of urban life, and insecurity is a priority category in the quality of life in urban spaces. The big city of Tehran has the highest share of the population to urban population in the whole country and is the most criminal city in Iran. New readings of place an...
This paper, gives an answer for the Question 1.1 posed by Hitzler (Generalized metrics and topology in logic programming semantics, 2001) by means of "Topological aspects of d-metric space with d-neighborhood system". We have investigated the topological aspects of a d-neighborhood system obtained from dislocated metric space (simply d-metric space) which has got useful applications in the sema...
As explained in the lecture "Introduction", topological notions of connectedness and of the boundary of a subset are important for image analysis. The widely used concept of m, nadjacencies defines these notions not satisfactorily: different adjacencies for the foreground and background are only applicable for binary images. A subset has two boundaries: the inner and the outer ones. They do not...
