Computer Packages
Instructions on how to use each package are included in the attached README files.
We invite also to look at the code to produce the examples for the corresponding.
Don't hesitate to contact me if you have questions and/or comments!

EllipticCurves  Macaulay2  link
 It provides basic functionalities for computations with elliptic curves.
 Written in collaboration with Alessandro Oneto.
 The development is concluded.

AlgEt  Magma  link
 It provides functionalities to compute with orders in étale algebras over Q.
 In particular, one can compute isomorphism classes of modules and the monoid of the ideal classes of the fractional ideals of the order.
 A version of this package has been included in Magma 2.281 (without documentation).
 The version available through the link is faster and it will be maintained nd expanded.
 This packages is based on theory developed in Papers [3], [9], [10] and [13].

IdlClQuat  Magma  link
 It provides functionalities to compute the isomorphism classes of ideals of an order in a quaternion algebra.
 This is a collaboration with Harry Smit.
 Currently, there is no plan to expand it.
 This packages is based on theory developed in Paper [11].

AbVarFq  Magma  link
 It provides functionalities to
compute isomorphism classes of abelian varieties (in the ordinary case and over a prime field) and polarizations (in the ordinary case).
 The package will be updated to use the functionalities developed in AlgEt for increase speed.
 This packages is based on theory developed in Papers [3], [4] and [5].

PolsAbVarFpCanLift  Magma  link
 It provides functionalities to compute polarizations for squarefree isogeny classes of abelian varieties over a prime field even when they are not ordinary.
 The package will be updated to use the functionalities developed in AlgEt for increase speed.
 This packages is based on theory developed in Paper [7].
