WebIn a recent study about HVFs of the same spacetime, it was observed that there are many static cylindrically symmetric metrics admitting four HVFs, including three minimum KVFs and one proper HVF [ 19 ]. Out of these metrics, four are same as the metrics 5a, 5c, 5h and 5m obtained during our classification. WebSuppose we have a cylindrically symmetric vector field u, symmetric about the z axis. u = f ( r, z) e r + g ( r, z) e z. Now, we have ∂ e z ∂ x = 0 and the same for y. The components of u in the x and y directions are: where ϕ is the polar angle. As x = r cos ϕ, 1 = ∂ r ∂ x cos ϕ − r ∂ ϕ ∂ x sin ϕ. Also, r = x 2 + y 2 so ∂ ...
