Abstract
In this paper we study the Goldman bracket between geodesic length functions both on a Riemann surface of genus with holes and on a Riemann sphere with one hole and orbifold points of order two. We show that the corresponding Teichmüller spaces and are realised as real slices of degenerated symplectic leaves in the Dubrovin--Ugaglia Poisson algebra of upper--triangular matrices with 1 on the diagonal.
