“…The solutions of NVN equation (1.1) with constant asymptotic values at infinity u(ξ, η, t) =ũ(ξ, η, t) + u ∞ =ũ(ξ, η, t) − , whereũ(ξ, η, t) → 0 as ξ 2 + η 2 → ∞, and with the functional parameters α k (ξ, η, t) and β k (ξ, η, t) defined in (1.11) and (1.8) are given by the general determinant formula [26] …”
