  2. Computer representation of surfaces - Wikipedia

    en.wikipedia.org/wiki/Computer_representation_of...

    A surface may be composed of one or more patches, where each patch has its own U-V coordinate system. These surface patches are analogous to the multiple polynomial arcs used to build a spline. They allow more complex surfaces to be represented by a series of relatively simple equation sets rather than a single set of complex equations.

    Mirzakhani was awarded the Fields Medal in 2014 for "her outstanding contributions to the dynamics and geometry of Riemann surfaces and their moduli spaces". [37] The award was made in Seoul at the International Congress of Mathematicians on 13 August. [38] At the time of the award, Jordan Ellenberg explained her research to a popular audience:

  4. Riemann surface - Wikipedia

    en.wikipedia.org/wiki/Riemann_surface

    There are several equivalent definitions of a Riemann surface. A Riemann surface X is a connected complex manifold of complex dimension one. This means that X is a connected Hausdorff space that is endowed with an atlas of charts to the open unit disk of the complex plane: for every point x ∈ X there is a neighbourhood of x that is homeomorphic to the open unit disk of the complex plane, and ...

    By reduction to the alternative case that c 2 (s) = s, one can study the rotationally symmetric minimal surfaces, with the result that any such surface is part of a plane or a scaled catenoid. [ 44 ] Each constant- t curve on S can be parametrized as a geodesic; a constant- s curve on S can be parametrized as a geodesic if and only if c 1 ′(s ...
