Discrete Theory of Real Riemann Surfaces
Analysis
Key Takeaways
- •Develops a discrete theory of real Riemann surfaces.
- •Uses quad-graphs and a discrete Cauchy-Riemann equation.
- •Classifies topological types of discrete real Riemann surfaces.
- •Constructs a symplectic homology basis adapted to the discrete involution.
- •Proves a canonical decomposition of the discrete period matrix.
“The discrete period matrix admits the same canonical decomposition $Π= rac{1}{2} H + i T$ as in the smooth setting, where $H$ encodes the topological type and $T$ is purely imaginary.”
