On Significant Pointwise Contractions and Annular Contractions
Ovidiu Popescu
In the current paper, we introduce the class of \textit{significant pointwise contractions}. This family of mappings extends the classical Banach contractions and also contains non…
On fixed point results in metric spaces for large triangle-perimeter contractions
Ovidiu Popescu
In this paper we introduce a corrected extension of Burton's theory of large contractions in the context of triangle-perimeter contractions introduced by Petrov. Combining these tw…
Fixed point theorem for generalized Chatterjea type mappings
Ovidiu Popescu, Cristina Maria Păcurar
We introduce a new type of mappings in metric space which are three-point analogue of the well-known Chatterjea type mappings, and call them generalized Chatterjea type mappings. I…
Some remarks on expansive mappings in metric spaces
Ovidiu Popescu, Cristina Maria Pacurar
The aim of this paper is to generalize the results on expansive mappings of Yesilkaya and Aydin from \cite{Yesilkaya}. We give some fixed point results for q-expansive mappings in…
