Some extensions of fixed point results over quasi-\(JS\)-spaces (Q294894)

Summary: We introduce the notion of quasi-\(JS\)-metric space. After defining the basic topological properties of quasi-\(JS\)-metric space, we investigate fixed point of certain mapping in the frame of complete quasi-\(JS\)-metric space. Our results unify and cover several existing fixed point theorems in distinct structures (such as standard quasi-metric spaces, quasi-\(b\)-metric spaces, dislocated quasi-metric spaces, and quasi-modular spaces) in the literature.
