I'm just wondering: in what field of mathematics are differential forms frequently used by professional mathematicians?
Differential forms are mathematical objects that are used to describe geometric quantities, such as vectors, lines, and planes, in a way that is independent of coordinates. They are a generalization of the concept of a vector field and are used in various branches of mathematics, including differential geometry and topology.
Differential forms have a wide range of applications in mathematics, physics, and engineering. They are used to study the geometry of manifolds, solve differential equations, and describe physical quantities, such as electric and magnetic fields. They also have applications in computer graphics, computer vision, and robotics.
One of the main advantages of using differential forms is that they provide a coordinate-free way of describing geometric quantities. This makes them particularly useful in situations where the choice of coordinates is arbitrary or changes frequently. Additionally, differential forms have a concise and elegant notation that simplifies calculations and proofs.
Differential forms are closely related to vector calculus, but they offer a more general and powerful framework for describing geometric quantities. In vector calculus, we use vector fields to describe quantities such as velocity, force, and electric fields. In contrast, differential forms can describe a much wider range of quantities and are not limited to vector fields.
Differential forms have numerous real-world applications in various fields, including physics, engineering, and computer science. Some examples include using differential forms to describe fluid flow, electromagnetic fields, and deformation of materials. They are also used in computer graphics to model and manipulate 3D shapes and in computer vision to analyze and understand images.
