  1. Envelopes of Geodesics on Ellipsoids

    Given a family of curves, an " envelope " of the family is a curve which is at some point tangent to every curve in the family. An intuitive example of an envelope consists of a family of lines in $\mathbb{R}^2$, whose envelope is a parabola...

  3. Steiner's Surface

    Recall the discussion of double points on quartics from Quartics with Tetrahedral Symmetry . Kummer showed [1] that such surfaces paramaterised by $\lambda, \mu$ have 16 double points (counting those in complex projective space) when $...

  5. Asymptotic Curves

    Many of our surfaces of revolution exhibit "asymptotic curves" (also referred to as "asymptotic lines"). These are defined in an analogous manner to geodesics . A geodesic has constant zero  geodesic curvature , while an asymptotic curve...

  6. Constant Mean Curvature Surfaces

    The " mean curvature " at a point on a surface is defined as the average $(\kappa_{1} + \kappa_{2})/2$ of its two principal curvatures . We can construct surfaces of revolution of constant mean curvature by rotating a special type of...
