Sage Days 15 Project Ideas

These are project ideas for Sage Days 15

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 mostly up and running. He's about to work on creating the associated chain complex.
  • B. Antieau has rudimentary simplicial complex morphisms, and is working on the functor to morphisms of chain complexes. No classes are implemented yet.

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, Benjamin Antieau, 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.

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.
