[sage-devel] printing and latex representation of multivariate polynomials

2009-07-17 Thread Alex Ghitza
Hi, I've been working on making the printing of polynomials prettier and more consistent between the univariate setting and the multivariate one. There is one ticket (with patch) on trac now at http://trac.sagemath.org/sage_trac/ticket/6551 which focuses on the case of exact coefficients and f

There is a bit of a catch-22 with polybori and mpfr on 't2' which I believe makes a need for http://trac.sagemath.org/sage_trac/ticket/6438 to be incorporated in 4.1.1, so it needs a reviewer, despite the fact I agree it is not the easiest patch to review. It is complicated by the facts that

2009-07-17 Thread Marshall Hampton
I'm probably in the minority on this, but I think tachyon being totally broken in sage-4.1 is bad enough that a sage-4.1.0.1 should be released as soon as possible with this fixed, not waiting for the 4.1.1 cycle to finish in two weeks. At the very least, perhaps sagenb can be patched. -Marshall

It will not be as easy as you think to modify jsMath to use @font-face web fonts. First, IE uses EOT fonts, while everyone else uses TTF and OTF fonts (and DON'T handle EOT fonts). Also, EOT fonts are keyed to a particular server, so they would have to be modified every time you want to serve th
