Period matrices and homological quasi-trees on discrete Riemann surfaces

Wai Yeung Lam, On-Hei Solomon Lo, Chi Ho Yuen

We study discrete period matrices associated with graphs cellularly embedded on closed surfaces, resembling classical period matrices of Riemann surfaces. Defined via integrals of…
