Analyzing Stability and Data Dependence Notions by a Novel Jungck-Type Iteration Method

open access: yesJournal of New Theory, 2023
Finding the ideal circumstances for a mapping to have a fixed point is the fundamental goal of fixed point theory. These criteria can also be used for the structure under investigation.

Battery Swapping Station Pricing Optimization Considering Market Clearing and Electric Vehicles’ Driving Demand

open access: yesEnergies, 2023
With the development of the new energy vehicle market, the pricing of battery swapping stations (BSS) is becoming a concern. The pricing models of BSS usually only consider the interaction between the distribution system operator (DSO) and the BSS or ...

An Example of Data Dependence Result for The Class of Almost Contraction Mappings [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2020
In the present paper, we show that $S^*$ iteration method can be used to approximate fixed point of almost contraction mappings. Furthermore, we prove that this iteration method is equivalent to CR iteration method  and it produces a slow convergence ...
