- Abstract
The objective of this paper is to prove the existence, non-existence and the sign of convex and convex-concave solutions of the third-order non-linear differential equation f‴ + f″ + βf′(f′ - 1) = 0 satisfying the boundary conditions f (0) = α ∈ ℝ, f′ (0) = b < 0 and f′ → λ as t → + ∞ where λ ∈ {0,1} and β < 0. The problematic arises in the study of the Mixed Convection Boundary Layer flow over a permeable vertical surface embedded in a Porous Medium according to the mixed convection parameter b<0, the permeable parameter α ∈ ℝ and the temperature parameter β < 0.
