Computational Mathematics Projects

• Continued Fraction Period for Quadratic Surds (continued_fractions)

  Fast Sage code for computing the period (and pre-period) of the continued fraction expansion of a quadratic irrational number.

• Demazure character formula (demazure)

  Computing the Demazure character formula in Sage. This is code to be contibuted to the combinat/root_system/weyl_character module.

• KPJ Strata (KPJStrata)

  Enumeration of Kraft-Procesi-Johnson strata in the Enhanced Nilpotent Cone. This project is part of the publication "Normality of orbit closures in the enhanced nilpotent cone".

• Zelevinsky Resolutions and CSM Classes (csm)

  This project contains Sage code for doing combinatorics related to Zelevinsky Resolutions and computing Chern-Schwartz-MacPherson classes of Schubert varieties in Grassmanians. See the publication.
