On the continuity of functions [PDF]
, 2007 Some theorems on continuity are presented. First we will prove that every convex function f :Rn -> R is continuous using nonstandard analysis methods. Then we prove that if the image of every compact (resp. convex) is compact (resp.

Localic maps constructed from open and closed parts [PDF]
, 2017 Assembling a localic map f:L→M from localic maps f_i:S_i→M, i∈J, defined on closed resp. open sublocales (J finite in the closed case) follows the same rules as in the classical case. The corresponding classical facts immediately follow from the behavior

On collectionwise Hausdorff bitopological spaces [PDF]
, 2012 In this work, we introduce the concept of collectionwise Hausdorff bitopological spaces by using p1 -open sets. Further, we also study the relations of collection wise Hausdorff spaces with some separation axioms and paralindeloff bitopological ...

A Frictionless Economy With Subotimizing Agents [PDF]
The existence of short-term monetary equilibrium in a frictionless economy with suboptimal agents is proved for any (reasonable) given interest rate. Separability ideas (as defined in Decision Theory) are applied.

, 2014 The author uses the Baire category theorem to prove the existence of nowhere differentiable functions in C([0,1]). Precisely, the author proves the following: Theorem 1. There exist continuous functions on the interval [0,1] which are nowhere differentiable. In fact, the collection of all such functions forms a dense subset of C([0,1]).
