In mathematics, "df" typically stands for "differential form." A differential form is a concept from calculus and differential geometry that generalizes the concept of a function. It is a mathematical object that can be integrated over a manifold, and it plays a fundamental role in the study of calculus on higher-dimensional spaces. Differential forms are used to express concepts such as integration, differentiation, and the geometry of curves, surfaces, and higher-dimensional spaces. **
