Notes

The surface element at a given point of a surface is given by:

d A = g d u d v

where $u$ and $v$ denote the Gaussian surface coordinates and $g$ denotes the determinant of the metric tensor (ISO 80000-2: Mathematics) at the particular point.

The symbol $d σ$ is also used for the surface element.

L'élément de surface en un point donné d'une surface est donné par:

d A = g d u d v

où $u$ et $v$ désignent les coordonnées gaussiennes de surface et $g$ le déterminant du tenseur (ISO 80000-2: Mathematics) métrique en ce point particulier.

Le symbole $d σ$ est également utilisé pour l'élément de surface.
