| Summary: | We discuss bases of the space of holomorphic quadratic differentials that are dual to the differentials of Fenchel–Nielsen coordinates and hence appear naturally when considering functions on the set of hyperbolic metrics which are invariant under pull-back by diffeomorphisms, such as eigenvalues of the Laplacian. The precise estimates derived in the current paper form the basis for the proof of the sharp eigenvalue estimates on degenerating surfaces obtained by the authors in another paper. |
