Computing Puiseux Expansions at Cusps of the Modular Curve X0(N)
The goal in this preprint is to give an efficient algorithm to compute
Puiseux expansions at cusps of X0(N). It is based on a relation with a
hypergeometric function that holds for any N.Comment: 4 page
On Hirzebruch invariants of elliptic fibrations
We compute all Hirzebruch invariants for , , and
elliptic fibrations of every dimension. A single generating series
is produced for each family of fibrations such that the coefficient
of encodes over a base of dimension , solely in terms
of invariants of the base of the fibration
