Theoretical: * simple facts from algebraic geometry, singularity theory, finite fields;
* theorem of Hasse-Weil, estimating the number of rational points on an absolutely irreducible projective curve C defined over a finite field (g=arithmetic genus=25):
# C ( Fp ) >  p+1 - 2g*sqrt(p)     (> 0 if p>2530);
* simple facts from the theory of standard bases;
Computational: * Gröbner basis computations without content extractions
* multivariate factorization
* resolution of plane curve singularities
* primary decomposition
