... the mappings f and g is continuous, and theysatisfy fX ⊂ gX.Thenf and g have a unique common fixed point in X.Using property E.A of the pair f, g instead of commutativity and continuity, ... mentioned in 13. We give an example of a pair of mappings f, g satisfying 1◦ and 2◦, but which have no common fixed points, neither in the setting of metric nor in the setting of cone ... subset of X,thenf and g have a point of coincidence.This result can be proved in the setting of cone metric spaces putting “∈” instead of “max,” and also for the symmetric space X, D associated...
