In this paper, we study the existence and uniqueness of fixed points for mappings with respect to a $wt$-distance in $b$-metric spaces endowed with a graph. Our results are significant, since we replace the condition of continuity of mapping with the condition of orbitally $G$-continuity of mapping and we consider $b$-metric spaces with graph instead of $b$-metric spaces, under which can be gen...

in traditional bazaars social interactions, parallel to economic and movement interactions, created a mixed urban space which was dynamic, lively and attractive to the audience. however, modern shopping centers and shopping malls are economy focused and void of variety of urban spaces like traditional bazaars. the presence of public open spaces and urban squares undetectable from traditional ba...

‎By substituting the usual notion of open sets in a topological space $X$ with a suitable collection of maps from $X$ to a frame $L$, we introduce the notion of L-topological spaces. Then, we proceed to study the classical notions and properties of usual topological spaces to the newly defined mathematical notion. Our emphasis would be concentrated on the well understood classical connectedness...

Despite the global spread of English, it seems that voices from Persian-speaking teachers concerning English as an international language (EIL) teaching methods and materials are underrepresented. The present study set out to explore how nonnative Persian-speaking English language teachers respond to the increasing global dominance of EIL and native- and non-native-speakers’ language norms with...

Urban green space is one of the important solicitude for urban planners and designers due to their effects on quality of life. This research used HPM model to estimate economic value of urban green space, in a case study of trees in Velenjak residential place, Tehran Metropolitan Area in Iran. View determined the spread tree on the public spaces and neighbourhoods improve residential lan...
