Definition

divergence of $a$

divergence de $a$

$\nabla \cdot a = \sum_{i} \frac{\partial a_{i}}{\partial x_{i}}$

The operator $div$ should be written in bold face.

$\nabla \cdot a = \sum_{i} \frac{\partial a_{i}}{\partial x_{i}}$

Il convient d'écrire l'opérateur $div$ en caractères gras.

A mathematical concept as defined in ISO/IEC 80000 Part 2.
