From this matrix equation, we will show that an associate matrix is an element of the Siegel upper half space as well as a period matrix and a combinatorial period matrix.
In this section, we will introduce a new matrix which is uniquely determined by a triangulated Riemann surface as well as a period matrix and a combinatorial period matrix and call this new matrix the associate matrix of a triangulated Riemann surface.
Note that the associate matrix is well defined by choosing any Riemannian metric in the conformal class of the Riemann surface.
