This is a sequel of the work done on (strongly) monotonically monolithic spaces and their generalizations. We introduce the notion of monotonically kappa-monolithic space for any infinite cardinal kappa and present the ...

In recent years, Brazilian medium-sized cities have been considered as attractive poles for both internal migration flows, and for new corporate investments in industry, trades, services and real estate, emerging new ...

For a topological property P, we say that a space X is star Pif for every open cover Uof the space X there exists Y aS, X such that St(Y,U) = X and Y has P. We consider star countable and star Lindelof spaces establishing, ...

The Henri Lefebvre's theory of the production of space is nowadays one of the main debated contributions in contemporary social theory when the subject is the spatiality of social life. This paper has place in this discussion. ...

A neighbourhood assignment in a space X is a family O = {O-x: x is an element of X} of open subsets of X such that X is an element of O-x for any x is an element of X. A set Y subset of X is a kernel of O if O(Y) = U{O-x: ...

We give local, explicit representation formulas for n-dimensional spacelike submanifolds which are marginally trapped in the Minkowski space R1 n+2 , the de Sitter space dSn+2, the anti-de Sitter space AdSn+2 and the ...

We study whether the operator space V ∗∗ α ⊗ W∗∗ can be identified with a subspace of the bidual space (V α ⊗ W) ∗∗, for a given operator space tensor norm. We prove that this can be done if α is finitely generated and V ...

We extend Oprea's result that the Gottlieb group G1(S2n+1/H) is ZH (the center of H) and show that for a map f: A → S2n+1/H, under some conditions on A, we have G1 f (S2n+1/H) = ZHf*(π1(A)), the centralizer of the image ...

The real estate market has shown over the last decades increasing centrality in the production of urban space in medium-sized cities in Brazil, presenting greater complexity in terms of their structure and content. In the ...
