Differential topology is the mathematical study of smooth manifolds.

Differential topology is a graduate-level concept that would be first encountered in a topology course.


Continuous Function: A continuous function is function with no jumps, gaps, or undefined points.
Derivative: A derivative is the infinitesimal rate of change in a function with respect to one of its parameters.
Topology: (1) As a branch of mathematics, topology is the mathematical study of object's properties that are preserved through deformations, twistings, and stretchings. (2) As a set, a topology is a set along with a collection of subsets that satisfy several defining properties.
