James-type constants for Birkhoff--James orthogonality and approximate isosceles
Zhiyao Fang, Ying Xu, Qi Liu +2
We introduce two James-type constants associated with approximate isosceles and approximate Birkhoff--James orthogonality in real normed spaces. The isosceles family coincides with…

Solving system of Urysohn type integral equation via bicomplex partial b-metric space
Gunaseelan Mani, Arul Joseph Gnanaprakasam, Yongjin Li +1
In this paper, we introduce the notion of bicomplex partial b-metric space and prove some common fixed point theorems. Our results generalize and expand some of the literature's we…
