Two open problems in the fixed point theory of contractive type mappings on first-countable quasimetric spaces
Mitrofan M. Choban, Vasile Berinde
Two open problems in the fixed point theory of quasi metric spaces posed in [Berinde, V. and Choban, M. M., {\it Generalized distances and their associate metrics. Impact on fixed…
Multiple fixed point theorems for contractive and Meir-Keeler type mappings defined on partially ordered spaces with a distance
Mitrofan M. Choban, Vasile Berinde
We introduce and study a general concept of multiple fixed point for mappings defined on partially ordered distance spaces in the presence of a contraction type condition and appro…
A general concept of multiple fixed point for mappings defined on spaces with a distance
Mitrofan M. Choban, Vasile Berinde
Our main aim in this paper is to introduce a general concept of multidimensional fixed point of a mapping in spaces with distance and establish various multidimensional fixed point…

Selections, Paracompactness and Compactness
Mitrofan M. Choban, Ekaterina P. Mihaylova, Stoyan I. Nedev
In the present paper, the Lindelof number and the degree of compactness of spaces and of the cozero-dimensional kernel of paracompact spaces are characterized in terms of selection…
