Web19 de out. de 2024 · 1 Answer Sorted by: 2 As stated by Ninad, If T has a divergence it must be a vector field. And vector fields don't have gradients. But I think I see what you are looking for. If you have a vector field with divergence 0, it means your function T can be expressed as the curl of some other function ( locally ). Why is that? It helps to notice that:

Web7 de set. de 2024 · Figure 16.5.1: (a) Vector field 1, 2 has zero divergence. (b) Vector field − y, x also has zero divergence. By contrast, consider radial vector field ⇀ R(x, y) = − x, − y in Figure 16.5.2. At any given point, more fluid is flowing in than is flowing out, and therefore the “outgoingness” of the field is negative. WebThis condition is based on the fact that a vector field F is conservative if and only if F = ∇ f for some potential function. We can calculate that the curl of a gradient is zero, curl. ∇ f = 0, for any twice continuously differentiable f: R 3 → R . Therefore, if F is conservative, then its curl must be zero, as curl.
