摘要

The Teichmüller space can be coordinatized via the Fenchel–Nielsen length and twist parameters associated with a pants decomposition. For ciliated surfaces, one can alternatively use Thurston’s shear coordinates, whose transformation rules are particularly well-structured and naturally lead to cluster algebra structures.
