    Caristi’s Fixed Point Theorem in Cone Metric Space by Fatemeh Lael, Naeem Saleem, Reny George

    Published 2022-01-01
    “…In addition, we partially addressed an open problem in which Caristi-Kirk fixed point result in cone metric spaces reduces to a classical result in metric spaces and provided a brief justification for a partial positive answer to this open problem using Caristi-Kirk fixed point theorem on uniform space. The proofs given to Caristi-Kirk’s result vary and use different techniques.…”
