%0 Journal Article %T Discrete period matrices and related topics %A Christian Mercat %J Mathematics %D 2001 %I arXiv %X We continue our investigation of Discrete Riemann Surfaces with the discussion of the discrete analogs of period matrices, Riemann's bilinear relations, exponential of constant argument, series and electrical moves. We show that given a refining sequence of critical maps, the discrete period matrix converges to the continuous one. %U http://arxiv.org/abs/math-ph/0111043v2
