In my work on group cohomology, I was bitten by the fact that Singular limits integers to 32 bit in the coefficients of Hilbert series. By consequence, examples such as the following from #20145 fai…

The idea of this work is to add some functions to linear_code.py and new decoding algorithms.
Theory and algorithms are taken from: *I. Marquez-Corbella. A combinatorial Commutative Algebra Approac…

During SD10 in Nancy, Michael Brickenstein and Burcin Erocal worked on making Plural (the non-commutative extension of Singular) accessible from Sage. Burcin and Michael also worked at the Plural wr…

2009/04/06 The first release candidate of PolyBoRi 0.6 is available
for download. It comes with a PEP8-conforming python interface and
new algorithms: FGLM and (experimental) parallel process…

I've already had two requests just today to solve simple equations modulo n.
Here is code to be pasted into the notebook that can do it:
```
def solve_mod(eqns, modulus):

Return all so…

I stumbled upon the following issue when inverting elements in `MPolyQuo`s over number fields. Try the following code:
```julia
P, t = QQ["θ"]
p = t^2+1
kk = splitting_field(p)
R, (x,y,z) = kk[…

update giac to the latest version - probably related to the problem on #27385
from the source at www-fourier.ujf-grenoble.fr/~parisse/debian/dists/stable/main/source/giac_1.5.0-63.*
produced tarba…

Starting with 7.5beta2, sage seems to be unable to start giac. See giac-error.txt
Now compiling giac with --disable-lapack to avoid unwanted links with system libraries
update to giac 1.2.2-103. …

This patch implements
* the Spec of affine toric varieties.
* patches for algebraic schemes with singular ambient toric varieties
In particular, Sage can now compute the dimension and smoothness f…
