decomposition of - continuity in ideal topological
... The concept of ideals in topological spaces is treated in the classic text by Kuratowski [10] and Vaidyanathaswamy [16]. The notion of I -open sets in topological spaces was introduced by Jankovic and Hamlett [8]. Dontchev et al. [4] introduced and studied the notion of Ig -closed sets. Recently, Na ...

Uniform maps into normed spaces
... for the theory of uniform spaces as well as for applications in analysis. Therefore we do not want to choose a name for them before the whole theory is developed, and basic applications are shown. In § 5 a short survey of these spaces is given. If X is a uniform space we denote by aX the set X endow ...

... poset intervals is a poset interval, an open set in P can be written as an (arbitrary) union of open poset intervals. As an example, the usual topology on R is precisely the interval topology generated by the linear order on R. Remark. It is a common practice in mathematics to impose special compati ...
