In [Aghajani A, Abbas M, Roshan JR. Common fixed point of generalized weak
contractive mappings in partially ordered Gb-metric spaces. Filomat, 2013, in press], using
the concepts of G-metric and b-metric Aghajani et al. defined a new type of metric which
is called generalized b-metric or Gb-metric space. In this paper, we prove a common fixed
point theorem for three mappings in Gb-metric spaces which is not continuous. An example
is presented to verify the effectiveness and applicability of our main result.
