Learning Outcomes

  • analyze the intrinsic geometry of curves in space, such as arclength and curvature.
  • analyze the intrinsic geometry of surfaces in space, such as surface area, Gaussian curvature.
  • determine whether two surfaces cannot be related by an isometric bijection, due to different intrinsic geometry.
  • use the Gauss-Bonnet theorem to relate the geometry of an oriented surface without boundary to its topology.
