Common fixed points for four non-self mappings in partial metric spaces. (English) Zbl 07217179
Summary: We formulate a common fixed point theorem for four non-self mappings in convex partial metric spaces. The result extends a fixed point theorem by L. Gajić and V. Rakočević [Appl. Math. Comput. 187, No. 2, 999–1006 (2007; Zbl 1118.54304)] proved for two non-self mappings in metric spaces with a Takahashi convex structure. We also provide an illustrative example on the use of the theorem.
