Curves and Surfaces in Minkowski spaces: 08 hours (Athoumane Niang: UCAD, Senegal)<\/strong><\/h4>\n<\/div>\n<\/div>\n<\/div>\n
\n
\n
\n

The differential geometry of curves and surfaces can be recommended to first-year graduate students, strong senior students, and students specializing in geometry. The material is given in two parts.\u00a0<\/span><\/p>\n

    \n
  1. Theory of Curves in the plane and the three-dimensional Minkowski space.\u00a0The first part contains the standard theoretical material on differential geometry of curves. It contains a small number of exercises and simple problems of a local nature. We will focus on the following concepts:\u00a0Definition and methods of presentation of curves; Tangent line and Osculating plane; Length of a Curve; Curvature of a Curve; Torsion of a Curve; The Frenet Formulas and the Natural Equation of a Curve; etc…\u00a0<\/span><\/li>\n
  2. Extrinsic Geometry of Surfaces in Three-dimensional Minkowski spaces.\u00a0The second part contains the standard theoretical material on differential geometry of surfaces. We will focus on the following concepts:\u00a0Definition and Methods of Generating Surfaces; the Tangent Plane; First Fundamental Form of a Surface; Second Fundamental Form of a Surface; Some Classes of Curves on a Surface; The Main Equations of Surface Theory.<\/span><\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    Differential Geometry: 08 hours (Aissa Wade, USA)<\/strong><\/h4>\n<\/div>\n<\/div>\n<\/div>\n
    \n
    \n
    \n

    In this course, we will discuss the basic theory of smooth manifolds. In lecture 1, we define what it means for\u00a0M\u00a0to be a smooth manifold or for\u00a0M\u00a0to be a submanifold of another manifold. We discuss immersions, fiber bundles, and vector bundles. In lecture 2, we treat the tangent bundle, submersions, and the cotangent bundle. Lecture 3 deals with the exterior algebra and Stokes\u2019 Theorem. In lecture 4, we present some applications of Stokes Theorem.\u00a0<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
