some very basic knowledge of Lie theory may be useful, but it is not required.LEC TOPICS 1-10 Chapter 1: Local and global geometry of plane curves 11-23 Chapter 2: Local geometry of hypersurfaces 24-35 Chapter 3: Global. The lecture notes are divided into chapters. the standard basic notions that are taught in the first course on Differential Geometry, such as: the notion of manifold, smooth maps, immersions and submersions, tangent vectors, Lie derivatives along vector fields, the flow of a vector field, the tangent space (and bundle), the definition of differential forms, de Rham operator (and hopefully the definition of de Rahm cohomology) More Info Syllabus Lecture Notes Assignments Lecture Notes.some basic knowledge of topology (such as compactness) 5, before exposing the long and exciting history of Lie group discovery, we remarked that differential geometry is at the basis not only of General Relativity but of all those Gauge Theories by means of which XXth century Physics obtained a consistent and experimentally verified description of all Fundamental Interactions.a good knowledge of multi-variable calculus.For instance, for symplectic structures: one talks about almost symplectic structures (non-degenerate two forms) and their integrability is about the form being closed (Darboux theorem) for foliations one talks about sub-bundle of tangent bundle, and their integrability is equivalent to the involutivity (Frobenius theorem) etc etc. Finally, in the last two lectures, we will concentrate on the integrability of G-structures and the torsion of G-structures as obstruction to integrability. Here we will present the framework and examples such as: Riemannian metrics, distributions, foliations, symplectic structures, almost complex and complex structures.Ĥ. While along the way we will mention some examples of geometric structures (such as metrics), in the last parts of the course we will concentrate on a general framework that allows one to treat many geometric structures in an unified way: the framework provided by the theory of $G$-structures. This part will start with 1-2 lectures about the basic notions/facts from Lie groups that are needed here.ģ. One which concentrates on principal bundles and connections, and where we explain that, for principal $GL_n$-bundles, the resulting theory is equivalent to the one for vector bundles. Here we will also discuss the tubular neighborhood theorem.Ģ. One which concentrates on vector-bundles and connections (including parallel transport, curvature and the construction of the first Chern class). Provide an introduction to vector bundles (with application to tubular neighborhoods), principal bundles, connections, the general theory of geometric structures (G-structures) and their integrabiliy, mentioning examples such as Riemannian, complex or symplectic structures.ġ.
