This study visualizes knot genus using Seifert surfaces, offering a new method to understand knot structures. The SeifertView tool generates natural, informative surface depictions for educational knot theory exploration.

Area of Science:

  • Mathematics
  • Computational Topology
  • Computer Graphics

Background:

  • Knot genus is defined by Seifert surfaces, essential in knot theory.
  • Traditional textbook diagrams of Seifert surfaces obscure their true shape and structure.
  • A need exists for improved visualization methods in knot theory education.

Purpose of the Study:

  • To develop and present novel methods for visualizing Seifert surfaces of knots and links.
  • To create accurate and intuitive representations of knot structures and their associated surfaces.
  • To provide a direct visualization of knot genus through closed, oriented embedded surfaces.

Main Methods:

  • Generating Seifert surfaces from braid representations of knots and links.
  • Applying Seifert's algorithm to create initial surface depictions.

  • Utilizing physically based modeling for surface relaxation to achieve natural shapes.
  • Developing a method for generating closed surfaces that embed the knot, visualizing genus.

    • Main Results:

    • A novel approach to visualizing Seifert surfaces from braid representations is presented.
    • Physically based relaxation yields natural and familiar knot and surface shapes.
    • Closed embedded surfaces effectively visualize the genus of a knot.
    • All developed methods are integrated into the freely available SeifertView tool.

    Conclusions:

    • The SeifertView tool offers enhanced visualization of knot and link Seifert surfaces.
    • The methods provide clearer insights into knot structure and genus for educational purposes.
    • Improved visualization aids in understanding complex topological concepts in knot theory.
