      Penn State Dept of Mathematics - Summer REU Program

      The concept of a manifold will be introduced for the specific case of curves and surfaces embedded in Euclidean 3D space. We will start with the parameterization and geometry of a curve, and eventually surfaces. There will be some focus on curves and surfaces that satisfy variational equations, as these often correspond to things in the physical world.

      Some Recommended Texts: (background - partially covered)
      • Differential Geometry: Curves - Surfaces - Manifolds, by Wolfgang Kuhnel (AMS Library, 2002)
      • Differential Geometry of Curves and Surfaces, by Manfredo Do Carmo

      Some Recommended Papers:
      • The equations for large vibrations of strings, by Stuart Antman, American Mathematical Monthly 87 (1980), pp. 359–370
