[sage-support] Using newer version of Jupyter 5.0 under SageMath 8.0

2017-08-31 Thread Mauricio Calvao
Hi I have SageMath 8.0 installed under my Debian desktop and use it typically through Jupyter notebooks, particularly for SageManifolds calculations. I would like to select some cells from a given Jupyter notebook, and then copy and paste them to another different Jupyter notebook, in another t

Thanks for you report. It works fine for me 8.1.beta3 also on archlinux. Can you give more precision about: - how did you install sage 8.0? - does the rest of Sage looks ok? On 31/08/2017 08:38, Tavian Barnes wrote: The following simple expression crashes Sage 8.0 on Arch Linux: tavianator@cos

[sage-support] Data structure for partition refinement

2017-08-31 Thread Jori Mäntysalo
Sage has a static data structure SetPartition, and a dynamic structure DisjointSet that can *combine* blocks. Is there a "dual" structure of latter, something that would start from one big block and would have functions to *split* block? -- Jori Mäntysalo

[sage-support] Assuming a function is constant in computing later expressions

2017-08-31 Thread Mauricio Calvao
I have declared a function Omega of a single variable t through: Omega = function('Omega')(t) Afterwards, I have calculated a quantity whose generic result is given in terms of the derivative of Omega (let us call it dOmega), for instance: quanti = Omega(t)*cos(t) + dOmega(t) Since I know the
