“…Theorem 1. Let f , g, h and k be self-mappings of a metric space X satisfying the following condition ϕ(d(f x, gy), d(hx, ky), d(f x, hx), d(gy, ky), (5) d(hx, gy), d(f x, ky)) ≤ 0, for all x, y ∈ X , where ϕ ∈ Φ. If the pair (f, h) as well as (g, k) is occasionally weakly h-biased of type (A) and occasionally weakly k-biased of type (A), respectively, then f , g, h and k have a unique common fixed point.…”
