Overview:

In this library, new methods for factorization on polynomials are implemented for three types of algebras, all generated by 2*n, n in NN, generators (n'th Weyl, n'th shift and graded polynomials in n'th q-Weyl algebras) over a field K.
More detailled description of the algorithms and related publications can be found at @url{https://cs.uwaterloo.ca/~aheinle/}.
