... and (3. 93) , k (1) V (x) ≡ 1 2 ω · ψ, (3. 97a) k (2) V (x) ≡ (ω × u) · x =(x × ω) · u, (3. 97b) 114 3 Vorticity Kinematics ∂ϕ ∂t + 1 2 q 2 + φ ∗ + χ = C(t). (3. 145) Alternatively, since (3. 63) implies ... =0, where Ω is the Largangian vorticity defined by (3. 133 a). Therefore, due to the arbitrariness of c, we return to (3. 134 ), which is equivalent to (3. 130 ). Thus, we arrive at the...
