2019-06-20 01:44:29 -0500 | edited question | Opening "old" Sage Notebooks in Jupyter: not UTF-8 encoded I've decided to pay attention to the "Sage Notebook is Deprecated" message at the top of all of my Notebooks, and convert everything into Jupyter. So it seems that I'm got Jupyter running on my system (through Anaconda), but when I save all my SageMath notebooks (as .sws files, since that seems to happen by default), and open them in Jupyter, (I'm running Jupyter with "sage -n jupyter"), I get the message in the notebook that the file is not UTF-8 encoded, and nothing else (sorry, I can't for the life of me seem to cut and paste this exact message from the Jupyter notebook...). I did a little searching and at least discovered this: So this file (and all my Sage Notebook Files) have "binary" listed as the character set. That seems bad to me - if it's a character set, shouldn't it be ASCII at least, or something? Anyone know how I can get these notebooks into Jupyter? I can go back and save them as something different if I knew what I needed to do. |

2019-04-27 02:29:19 -0500 | edited question | Scaling and tensor product for Lie Groups I am new to any coding. I want to compute a tensor product of several scaled weights of a lie group and I can't get this to work. Looking at the sage math pages for Weyl Character Rings, I figured out how to do tensor product decompositions, e.g. if you put in then it gives you the decomposition of the above tensor product (where the weights (1,1,1), etc., are written in the fundamental weight basis). I want to compute something like where each of the weights is scaled by 2, but without having to manually scale the weights (so I can implement this in some more general code). You can scale weights by entering e.g. A2(1,1,1).scale(2), and this gives you A2(2,2,2), BUT this only works for me when I add .ambient() to the end of the definition of A2 above. HOWEVER after I add .ambient(), the tensor products no longer work! (If I try to do a tensor product after adding the .ambient(), it just adds the vectors componentwise...) If anyone is familiar with how to do this sort of thing, your help would be greatly appreciated! Thanks. |
