the goal of this article is mapping urban management science. the main question of the research is “what are the subject areas of urban management science and how is the relation between these subject areas?” the map of urban management science can help to recognize urban management and its subject areas and can help policy makers to get familiar with the priorities in this subject area. for th...

A Smarandachely k-signed graph (Smarandachely k-marked graph) is an ordered pair S = (G,σ) (S = (G,μ)) where G = (V, E) is a graph called underlying graph of S and σ : E → (e1, e2, ..., ek) (μ : V → (e1, e2, ..., ek)) is a function, where each ei ∈ {+,−}. Particularly, a Smarandachely 2-signed graph or Smarandachely 2-marked graph is called abbreviated a signed graph or a marked graph. Given a ...
