Overview

The study shows how taut fillings arise from extending a triangulation, indicating potential principles for higher dimensions.

Key Points

  • Any taut filling of a 2-sphere corresponds to an extended shellable triangulation of the 3-ball.
  • The key theorem demonstrates that taut fillings maintain the property of splitting under various unions.
  • Integral 2-cycles are filled by integral 3-chains that have minimal L1-norm, a critical measure of efficiency.
  • No conclusions can be drawn regarding optimal fillings for spheres in dimensions higher than three.
