👉 A geodiferous is a type of surface element in the theory of differential geometry. It is defined as an element that can be expressed as a sum of two or more scalar functions, and its value at any point on the surface of the object it describes is given by these scalar functions. Geodifferentials are fundamental to understanding geodesics, which are curves on a surface that minimize the distance between them. They are also used in the study of fluid mechanics and elasticity theory.
