TL;DR: In this article, the magneto hydrodynamic boundary layer flow with heat and mass transfer of Williamson nanofluid over a stretching sheet with variable thickness and variable thermal conductivity under the radiation effect is examined.

TL;DR: ( α, δ, β )-cut and strong ( α , δ , β)-cut of PFS have been defined and decomposition theorems of P FS are proved and picture fuzzy arithmetic based on extension principle has been performed with examples.

TL;DR: In this paper, the authors considered the notion of α - ψ -contraction in the setting of F -metric spaces and presented some fixed point and coupled fixed point results in the generalized setting.

TL;DR: In this paper, numerical study of unsteady magnetohydrodynamic natural convective heat and mass transfer of a viscous, rotating fluid, electrically conducting and incompressible fluid flow past an impulsively moving vertical plate embedded in porous medium in the presence of ramped temperature, thermal radiation, hall current, thermal diffusion and diffusion thermo is investigated.

TL;DR: In this article, an efficient numerical method is used for solving 2D-mixed Volterra-Fredholm integral equations based on 2D OBP together with collocation method.
