This site is obsolete. New and updated versions of the algorithms can be found in the new site:
Nevertheless some examples and tutorials from here can still be useful. 

------------------------------------
This site contains several algorithms useful to study group actions on Riemann surfaces and on Abelian varieties. Papers related are:
"Adapted hyperbolic polygons and symplectic representations for group actions on Riemann surfaces" by Antonio Behn, Rubí E. Rodríguez and Anita M. Rojas.
"A SAGE package for equisymmetric stratification in Mg" by A. Behn, A. M. Rojas, M. Tello-Carrera.
"Completely decomposable Jacobian varieties" by Jennifer Paulhus and Anita M. Rojas.

The SAGE implementation of algorithms described in these papers is now available here.
