Abstract In this paper, we investigate the conditions on control mappings $\psi ,\varphi :(0,\infty )\rightarrow \mathbb{R}$ ? , ? : ( 0 ? ) ? R that guarant...

We recently developed a chlorophyll fluorescence method (activated F0 rise) for estimating if light wavelength preferably excites PSI or PSII in plants. Here, the was tested green microalgae: Scenedesmus quadricauda, ecornis, fuscus, Chlamydomonas reinhardtii, Chlorella sorokiniana, and Ettlia oleoabundans. The species displayed plant-like action spectra of rise, suggesting that PSII/PSI absorp...

In the setting of fuzzy metric spaces (FMSs), a global optimization problem (GOP) obtaining distance between two subsets an FMS is solved by tripled fixed-point (FP) technique here. Also, weak contractions (WTCs) for that are given. This was known before in space (MS) as proximity point (PPP). The result correct each continuous τ—norms related to FMS. Furthermore, non-trivial example illustrate...

In this paper, we introduce cyclic weak φ−contractions in fuzzy metric spaces and utilize the same to prove some results on existence and uniqueness of fixed point in fuzzy metric spaces. Some related results are also proved besides furnishing illustrative examples.
