Abstract: The plumbing parameters gives local coordinates near the
boundary of the Delign-Mumford compactification of the moduli spaces of
Riemann surfaces. In this talk we introduce a new method to construct
smooth abelian differentials on Riemann surfaces near an arbitrary
degenerated Riemann surface, in terms of the plumbing parameters. This
method further allows us to compute the degeneration of the period
matrices, generalizing results of Yamada and Taniguchi.
