Abstract

We develop an abstract framework for coupled period--realization of meromorphic 11--forms on punctured Riemann surfaces. A configuration datum CC gives the combinatorics and determines a restricted character domain ΔCHom(Γg,n,C)2\Delta_C\subset\mathrm{Hom}(\Gamma_{g,n},{\mathbb C})^2 with a scale--fixed slice ΔCsc\Delta_C^{\mathrm{sc}}. Assuming Teichm\"uller--regularity, degeneration detection, and pushability, we prove that there is point in ΔCsc\Delta_C^{\mathrm{sc}} which corresponds to a surface carrying two meromorphic differentials realizing any prescribed restricted pair. This abstracts the Weber--Wolf extremal--length minimization method while constructing minimal surfaces.
