Sage Days 15 Project Ideas
These are project ideas for Sage Days 15
MSVC 2008 port of PARI-2.4.2.alpha0
- Do a port of PARI-2.4.2.alpha0 to MSVC 2008, including MPIR support.
Low Level Simplicial Sets, CW Complexes, and Morphisms for Simplicial Complexes and Chain Complexes
PEOPLE: S. Ault, B. Antieau
S. Ault has a CW Complex class up and running (including the chain_complex() method). The next step is to work on a homology_with_generators method within the ChainComplex
- B. Antieau has simplicial complex morphisms, and has the functor to morphisms of chain complexes.
- There are simplicial complex morphism and chain complex morphism classes, and there is a method on the former to produce and instance of the latter, including base rings, augmentation, chain v. cochain.
- Working on various associated complexes of a map, like graph, mapping_{cone,cylinder,path_space}.
- Working on fiber products.
- Prepping for induced maps on homology, cohomology, ring structure on cohomology.
Prime Pi
PEOPLE: Fredrik Johansson, William Stein, Robert Bradshaw
- Investigate implementing the Meissel, Lehmer, Lagarias, Miller, Odlyzko for computing the number of primes up to x.
Steenrod Algebra cohomology (Yacop integration)
PEOPLE: Christian, John Palmieri, S. Ault, Bob Bruner
A first version is already available. Here's a page with installation instructions: Yacop
Quaternion Algebras (implement odd power of p dividing level case)
PEOPLE: Alia Hamieh, Jerome Lefebvre, William Stein.
Sage/Magma Comparison Audit
PEOPLE: William Stein, Bill Hart, Robert Bradshaw, Alia Hamieh, Jerome Lefebvre.
See sagebeatsmagma and magma
CANCELLED (already in Sage!) Generalized Bernoulli Numbers
PEOPLE: William Stein
- There is a simple 2 or 3 line formula for generalized Bernoulli numbers in terms of non-generalized ones, which could be used to speed up the chi.bernoulli_number(k) command (for a Dirichlet character chi) by a factor of thousands.
