New fixed point theorems for θ - ϕ -contraction on b -metric spaces

In this paper, we define \(\theta\)-\(\phi\)-contraction on a \(b\)-metric space into itself by extending \(\theta\)-\(\phi \)-contraction introduced Zheng {et al.} [D. W. Zheng, Z. Y. Cai, P. Wang, J. Nonlinear Sci. Appl., \(\bf 10\) (2017), 2662--2670] in metric and also, prove \(\theta \)-type theorem the setting of spaces as well framework \(b\)-rectangular spaces. Moreover, give some applications to nonlinear integral equations. We also illustrative examples exhibit utility our results.
