**Spring 2022:** MATH 740 "Fundamental Concepts of Differential Geometry"

Description: This course will be a basic graduate introduction to differential geometry. Tentatively, we will start with some foundational material: defining manifolds, tangent bundle, vector bundles, the inverse and implicit function theorems, immersions and submersions, submanifolds, ideas of transversality. Then we will cover differential forms, integration on manifolds, Stokes' Theorem, and time permitting de Rham cohomology. After that we will get to Riemannian geometry. We will introduce and study Riemannian metrics, connections, geodesics, curvature, Jacobi fields, and the geometry of submanifolds. At the end we will try to cover some of the main classical theorems in global Riemmannian geometry, which relate curvature properties to topology, such as the Cartan-Hadamard Theorem and Myers' Theorem.
