Webof Divergence-Free Functions By Giovanni Sacchi Landriani and Hervé Vandeven Abstract. We study the best approximation of a divergence-free function by a diver-gence-free algebraic or trigonometric polynomial and we prove an optimal estimate. In a particular case we give also an optimal result for the polynomial approximation of a ... WebSep 7, 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.
