At least you can use the interface to GAP: sage: MS = MatrixSpace(QQ, 2) sage: m1 = MS([[0, -1], [1, 0]]) sage: m2 = MS

Alright. And for completeness, what's the issue with installing using conda?

Since you don't plan on doing development, you could install a binary release: https://github.com/3-manifolds/Sage_macOS

from virasoro import * works when there is a file named virasoro.py in the same directory (that's how I named my copy of

I don't know, have you tried it? You might want to provide your ideal I if you want a meaningful answer.

It seems like a strange thing to make a copy of a file you already have in your SageMath installation. You are talking a

Please add some complete code that actually runs. Do you mean something like this? R.<x> = PolynomialRing(QQ) f =

I'm not sure yet what the issue is. Could you please post the full error you get in your actual script? (You can edit yo

It is difficult to help without any specifics. Please add some (more or less minimal) complete runnable code that reprod

In the table at src/sage/knots/knot_table.py, knots are described as closures of braids. The (minimum) braid representat

Please make your code self-contained by adding a definition of gens (any example will do).

A workaround (which is probably not efficient) is: sage: A = Zmod(2**256) sage: R.<x,y> = PolynomialRing(A, imple

As far as I can tell this uses matplotlib.pyplot.hist which has the same issue, so you might want to ask the matplotlib

Simple answer: Once you have z12 assigned to a variable you can use it directly: sage: X = 162606730613419492752575632

Yes, you can do e.g. list(h) or tuple(h); I added it to my answer.

Here is a way: F = GF(23) A2.<x,y> = AffineSpace(F, 2) H = Hom(A2, A2) h0 = H([(x^2 + 1)/x, (x^2*y - y)/x^2]) h1

Could you please add the equivalent Macaulay2 code that works faster?

Here is a way: F = GF(23) A2.<x,y> = AffineSpace(F, 2) H = Hom(A2, A2) h0 = H([(x^2 + 1)/x, (x^2*y - y)/x^2]) h1

Sage is not smart enough to understand what you want. In the source code we can see it does handle lists and tuples as

You might also do some computations in the polynomial ring and use a pre-computed Gröbner basis G = I.groebner_basis() t

It works for me. Did you try restarting SageMath (to force it to load the package anew, since the package was first load

This could be an XY problem. Why do you want to iterate over the whole quotient ring? There could be a better way to do

This is something that could be built in and made easier for users. For now, I think it needs slight manual work. A vec

Conceptually the code should be trying to find the preimage of an element which is in the image of a map (if I understoo

Can you be more precise?

The construction goes like this (obtained by entering E.height_pairing_matrix?? into a SageMath session): for j in rang

Here is a more natural way to do it: sage: R.<y> = PowerSeriesRing(ZZ) sage: R(b.polynomial().map_coefficients(la

Here's a way to do the elimination properly: R = PolynomialRing(QQ, names=['a','b','c','d','e','f','g'] + [f'm_{i}{j}'

Thanks @Max Alekseyev, I updated the answer making use of your hint.

Here's a way to do the elimination properly: R = PolynomialRing(QQ, names=['a','b','c','d','e','f','g'] + [f'm_{i}{j}'

With e.g. g[0,0].expr() which is a symbolic expression you'll be able to do more.
