2019-04-30 02:07:59 +0200 | commented question | Symbolic sum/product of Laurent/power series c[i] and d[i] are indexed symbolic variables. I'm trying to do symbolic calculation on power/Laurent series and extract the coefficients at the end. The snippet I wrote was my single example in detail. The tricky part about this for me is the symbolic variables n, c[i], and d[i]. I need to coefficients at the end to be expressed in forms of sums or products running over i. |

2017-07-14 18:08:01 +0200 | asked a question | Map between projective curves defined in an extension field For example, suppose I have the following 2 projective curves: I like to define a map from E to W that involves $\sqrt 2$ and $\sqrt 8$, which do not exist in k = GF(13), but do in an extension of k: So $w = \sqrt 2$ and $2w = \sqrt 8$. The map I like to define sends $(x:y:z)$ to $(wx:2wy:2wz)$. In this particular example, it's obvious that $(wx:2wy:2wz) = (x:2y:2z)$; but it's just a simple example do demonstrate the problem. Something like this doesn't work: Thank you. |
