Hahn-Banach type extension results for linear operators on asymmetric normed spaces
S. Cobzaş
We present some results related to Hahn-Banach extension theorem for linear operators on asymmetric normed spaces. L. Nachbin, Trans. Amer. Math. Soc. 68 (1950), proved that a Bana…
Ekeland, Takahashi and Caristi principles in preordered quasi-metric spaces
S. Cobzaş
We prove versions of Ekeland, Takahashi and Caristi principles in preordered quasi-metric spaces, the equivalence between these principles, as well as their equivalence to some com…
Compact bilinear operators on asymmetric normed spaces
S. Cobzaş
The paper is concerned with compact bilinear operators on asymmetric normed spaces. The study of multilinear operators on asymmetric normed spaces was initiated by Latreche and Dah…
Completeness in quasi-pseudometric spaces
S. Cobzaş
The aim of this paper is to discus the relations between various notions of sequential completeness and the corresponding notions of completeness by nets or by filters in the setti…
Ekeland, Takahashi and Caristi principles in quasi-pseudometric spaces
S. Cobzaş
We prove versions of Ekeland, Takahashi and Caristi principles in sequentially right -complete quasi-pseudometric spaces (meaning asymmetric pseudometric spaces), the equivalenc…
B-metric spaces, fixed points and Lipschitz functions
S. Cobzaş
The paper is concerned with b-metric and generalized b-metric spaces. One proves the existence of the completion of a generalized b-metric space and some fixed point results. The b…
