it is strange that your install actually tries to install Sage's "patch". ./configure in the end prints out a suggested list of packages to install in brew, and patch (more precisely, gpatch) should be one of them. On Mon, 20 Jul 2020, 00:21 Daniel Bump, wrote: > On Sunday, July 19, 2020 at

Hi Siddharth, That sounds like a good idea. What you will need to do is create a number of tickets to add in the corresponding functionality. Once you have a proposal (which you can ask questions on said tickets), it will be reviewed, where suggestions and comments will be given on possible d

Hi John, Your question is a good one, to look at the places where the notion that 0 has no degree causes extra effort.I have strong memories of having to go through minor but annoying contortions to deal with this, both in sage and in MAGMA, for decades now, but don't have examples fresh in

Hello, I've been learning differential geometry and discrete differential geometry for around a year now. I understand that SAGE now has a sage-manifolds which adds support for defining smooth manifolds as well as riemannian manifolds. I am interested in providing "discretized" versions of sm

I don't think homebrew recommends you linking it since Mac ships with makeinfo and install-info, but putting it on the path to build sage seems fair. On Sunday, July 19, 2020 at 10:15:35 AM UTC-4 dei...@gmail.com wrote: > Thanks, this worked (it was already installed, but not linked). > > > On

Hi Bob, Mathematically, a classical example of a graded object is a polynomial ring, and non-topologists often consider nonhomogeneous polynomials, for reasons that are beyond me. But once you do that, it seems that you're forced to live in a direct sum. Sage could have two different structures
