Categorical Closure Operators,A brief survey of the development of the theory of closure operators is presented. Results concerning the applications of the theory to epimorphisms, separation, compactness and connectedness are also included together with a number of supporting examples.

,The Naturals are Lindelöf iff Ascoli Holds,It is shown that in . (i.e., Zermelo-Fraenkel set theory without the Axiom of Choice) the classical Ascoli Theorem holds iff ℕ is a Lindelöf space.

https://doi.org/10.1007/978-3-319-01183-780s, Galois connections were generalized to connections, and in the 1990s, a counterpart to Galois connections, called Lagois connections, were discovered. Lagois connections, as the name suggests, are similar to Galois connections; however, the “movement” from arbitrary points to image points - whi

Conceptualizing Drivers of Forest Loss,the Wallman compactification becomes functorial. Later, Bentley and Naimpally generalized Harris’ result to the setting of topological spaces endowed with the structure of a separating base in the sense of Steiner. In the present paper, the generalization is carried one step further to the setting o
