A fixed point theorem for mappings with a contractive iterate in rectangular $b$-metric spaces
Z. Mitrović
Abstract
In this paper, we give a proof for Sehgal-Guseman
theorem of fixed point in rectangular $b$-metric spaces. Our result is supported with a suitable example. As a corollary of our results, we obtain fixed point results of
contraction mappings in $b$-metric spaces.
