  • A discussion on a pata type contraction via iterate at a point 
    Karapınar, Erdal; Fulga, Andreea; Rakočević, Vladimir (2020)
    In this paper, we introduce the notion of Pata type contraction at a point in the context of a complete metric space. We observe that such contractions possesses unique fixed point without continuity assumption on the given ...
