2021-10-27 20:55:43 +0100 | marked best answer | Download mirrors and the Sage-Windows installer Hi All, I understand that many download mirrors of SageMath for Windows are inactive, they are stuck at SageMath 9.2, no trace of SageMath 9.3 for Windows or SageMath 9.4 for windows. What is the most reliable and active site to download the latest version of SageMath for Windows? Thanks, Daniel Volinski |

2021-01-10 11:07:26 +0100 | commented answer | Integral equation solver What I'd suggest now is to put this procedure and knowledge into a command so that there will be no need to do it manually. You will just need to write the Integral Equation and use this new command to obtain the required solution. Daniel Volinski |

2021-01-09 04:23:46 +0100 | commented answer | Integral equation solver Thank you, I was looking for something like what you see in Solve a Volterra Integral Equation , not something manual as you did but a command that would give the solution once I give the equation. Daniel Volinski |

2021-01-08 11:04:10 +0100 | asked a question | Integral equation solver Can Sage solve integral equations (where the unknown is a function and the equation involves integrals), either analytically or numerically? References: For example, can Sage solve a Volterra equation of the second kind, such as The solution is expected in the form $y(x) = ...$ where the right hand side is an explicit function of $x$ not involving $y$. Notice in the example the function $y$ appears in two places, once in the left hand side and the other inside the integral sign. I am looking for something like what you see in i.e., a command that would give the solution once I give the equation. |

2020-08-29 10:34:23 +0100 | commented answer | When affine_connection is empty I would go for something more suave, some kind of error that would not stop the calculation of further cells in the notebook, after all, it is not an error that can cause other errors, you just have to give some content to the affine connection (or the tensor field) and everything should be all right. |

2020-08-25 22:25:12 +0100 | asked a question | When affine_connection is empty Hi All, I'm using SageMath 9.1 on Windows Native. When affine_connection has no content and I display it, I get a ValueError that stops the computation. IMO it should display something like 'Empty' or 'Null' or '{}' but not an error. Daniel |

2020-08-25 22:12:29 +0100 | asked a question | Error when I had some show commands Hi All, I'm using SageMath 9.1 on Windows Native. I'm using the following documentation file: Curve. If I use the very last two parts of that file: Then the result is fine as it should. But If I add the following two lines after the definition of Then the very last command of the file gives me a ValueError: ValueError: no basis could be found for computing the components in the Vector frame (R, (d/dth,d/dph)) with values on the Open subset A of the 2-dimensional differentiable manifold M Is this a bug?

2020-08-12 20:13:41 +0100 | asked a question | Sagemanifolds display has deteriorated Hi All, I've noticed a deterioration in the display of objects in SageManifolds, I'm using the following code: In SageMath for Windows Native 8.1 the display command would display the Greek letter omega. On the other hand in SageMath for Windows Native 9.0 and 9.1 the display command displays the word omega, not the Greek letter. Is this a bug? Daniel |
