What is the difference between geometric topology and algebraic differential topology?
Geometric topology and algebraic differential topology are two branches of mathematics that study the topology of smooth manifolds. Geometric topology focuses on the geometric properties of smooth manifolds, such as their curvature and homology groups. Algebraic differential topology, on the other hand, focuses on the algebraic properties of differential forms on smooth manifolds.
One of the main differences between geometric topology and algebraic differential topology is the way in which they approach the study of smooth manifolds. Geometric topology typically uses geometric techniques, such as Morse theory and Riemannian geometry, to study the topology of smooth manifolds. Algebraic differential topology, on the other hand, typically uses algebraic techniques, such as de Rham cohomology and the theory of characteristic classes, to study the topology of smooth manifolds.
Another difference between geometric topology and algebraic differential topology is the types of problems that they study. Geometric topology is typically concerned with problems related to the geometry of smooth manifolds, such as the existence of closed geodesics or the topology of submanifolds. Algebraic differential topology, on the other hand, is typically concerned with problems related to the algebraic properties of differential forms on smooth manifolds, such as the de Rham cohomology groups or the Chern classes.
