20180616 11:51:28 0500  commented answer  RecursionError when installing SageMath 8.2 Note that this path issue only seems to be a problem when running Sage for the first time. You should be able to reinstall python3 again with homebrew and use Sage without any problem (until you upgrade versions). 
20180613 05:00:51 0500  answered a question  Algorithm for finding a defining polynomial for an unramified extension? The short answer is that this will depend on the way you defined your unramified extension. If, for instance, you defined it using If there's some other specific case you're interested in, perhaps you can edit your question to include the code that constructs that particular extension. What follows is "the long answer", or how I found this out, starting from knowing essentially nothing about algebraic number theory or any of SageMath's ANT functionality. Hopefully the description of the steps I took in diving into SageMath's source code will be helpful for you in finding the answers to any similar questions you might have in the future. Suppose we've defined R as follows: Then we can type to look at the docstring for this particular function. The resulting output, while somewhat helpful, does not explain what algorithm SageMath is using to compute it. However, it does contain a line pointing to the source code, something like: Now, it's a bit more convenient to look at this file online in e.g. the github mirror of the SageMath source code. I've linked to the specific line where the definition of In this case, it appears that this code simply returns We find that
In fact, we could have skipped some of the codediving above as SageMath's reference site has a thematic tutorial on padics, see the documentation of However, to find the details of the "generator chosen for $\mathbb{F}_q$", we must return to the code: The code implementing this can be found here, which uses the Looking at the relevant part of that code, we see that If we look at the code for the class

20180611 10:58:28 0500  answered a question  What is the SAGE command for calculating a Frobenius number It appears that this functionality has not been implemented in SageMath. This comment and the associated answer by Stan Wagon at MathOverflow state that the Mathematica function uses the algorithm described here: A15: Frobenius Numbers by Lattice Point Enumeration by David Einstein, Daniel Lichtblau, Adam Strzebonski, and Stan Wagon. Here is another paper describing an algorithm by Dale Beihoffer, Jemimah Hendry, Albert Nijenhuis, and Stan Wagon with different properties. This algorithm of Böcker and Lipták is described in Beihoffer et al as "very elegant and simple", so perhaps that might be something easier to try to code, depending on your needs.

20180302 10:22:20 0500  marked best answer  SageMath and interact / ipywidgets with jupyter I got the SageMath kernel working well inside my anaconda distribution's copy of jupyter, following these instructions, so I can open SageMath notebooks using anaconda jupyter and they run perfectly fine  almost. I would like to get interact elements / ipywidgets working when I use SageMath as a kernel in anaconda jupyter, but with my current configuration (hopefully described in sufficient detail below), I get the following error message in the console
and the notebook simply outputs the initial value of the function with no interactivity. I'm running SageMath 8.1 on macOS. I've been able to get interact elements and ipywidgets with SageMath code running in the SageMath jupyter notebook interface (not sure if this was necessary, but I ran
in the SageMath directory.) Everything works as expected, i.e. if I run
I get a slider widget which works. Similarly, examples from this interact tutorial on the SageMath wiki run perfectly fine in SageMath jupyter. I also have an uptodate anaconda install of jupyter where the ipywidgets nbextension has been enabled; the above ipywidgets code can be run in anaconda jupyter with the ordinary python kernel and works fine. [The real reason I am asking this question is I would like to figure out how to get interactive widgets working in jupyterlab with the SageMath kernel, but I'm guessing that if the above question can be answered, I can get everything else working as well.]

20180301 22:26:29 0500  answered a question  Sagemath 8.1 windows: Impossible to export jmol figure from Jupyter while it works with former notebook. I can confirm that there is an issue here with SageMath and jupyter but I don't have any solution, unfortunately. I just tested jmol in the following is probably not relevant You could also try installing the SageMath kernel into jupyter by following the instructions here, with appropriate modifications for Windows. Note that this requires more fiddling and you might find that interact elements don't work by default.
