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…
