2020-05-02 00:44:02 +0200 | asked a question | Best practice to save results of a function as a database I have a function defined inductively that taxes my computer quite a lot. It will help a lot if I can save its results somewhere, preventing it from unnecessary calculations. To simplify, assume that it's a function $f: \mathbb{N} \to \mathbb{N}$, where $f(0)=1$ and $f(i)$ depends on the value of $f$ at lower $i$'s. Imagine that I want to calculate $f(n)$ where $n \sim 10^{1000}$. Of course, I can do it by But I feel like this can be improved. Any idea? |

2020-04-16 19:47:17 +0200 | asked a question | Polynomial ring indexed over an abelian group (magma). Hi, I wonder if currently there's a cleaner way to do $x^v \cdot x^w = x^{v+w}$ in Sage, where $v, w$ are some vectors in a vector space? Once a basis ${v_1, \cdots v_n}$ for the vector space is chosen, this can be done by identifying $x_i$ with $x^{v_i}$, and use the multivariate ring $R[x_1, \cdots, x_n]$. However, I would like to do this in an intrinsic manner, i.e. not choosing a basis. More generally, I think for any element $m$ in any magma $M$, we should be able to define an algebra $R[x^m|m\in M]$ over any given ring $R$. Notice that this is not the same as QuestionIs $R[x^m|m\in M$$ currently doable? If not, I might work on writing it. ApplicationA reason why I think it would be helpful: it can help calculating generalized characters of representations of quantum groups. |
