Re: [sage-support] Re: Canonical divisor help

The most pressing problem in sage at the moment seems to be that presently there only seem to be morphisms between schemes. You need rational maps for this (especially from a singular model, the map to a canonical model might only be a rational map). "SchemeMorphism" in Sage is a map

Re: [sage-support] Re: Canonical divisor help

That's actually trivially simple: if [f1,f2,f3] is the basis of your Riemann-Roch space, you just consider the map defined by [f1:f2:f3]. So you lift f1,f2,f3 to rational functions on the affine space that contains your curve: you just take the rational function representation and forget the

Hi, Do we have multiset in Sage or Python? I learned that Python 2.7 has Counter collection which implements multiset. If not, is there a simple construct to mimic multiset? Kwankyu -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send

[sage-support] Re: Need arbitrary Singular term orders

Hi Jeff, There was a bug in the matrix order of Sage. It did not allow negative integers in the string representation of a matrix order. That bug is fixed in the patch for trac #11316, which I just uploaded. Sorry for late reply. Kwankyu -- To post to this group, send email to sage-support

[sage-support] Confused about rmul and lmul

Hi, Below is a passage in the Reference manual on the coercion model: If R is the base of S (as in the first example), simply implement _rmul_ and/or _lmul_ on the Elements of S. In this case r * s gets handled as s._rmul_(r) and s * r as s._lmul_(r). The argument to _rmul_ and _lmul_ are

[sage-support] On .inputrc

Hi, If I put the following line \C-k: kill-whole-line into ~/.inputrc, Sage does not recognize it, that is, ctrl-k always does kill-line On the other hand, in IPython invoked by sage - ipython, ctril-k does kill-whole-line as expected. Why is it so? Does Sage set keys in its own way? Kwankyu

[sage-support] Getting a mirror image of a matrix

Hi, Does Sage have a command to get the mirror image matrix [3,2,1] [6,5,4] from the matrix [1,2,3] [4,5,6] ? It seems not... Then is there a simple trick to do that? Of course, I can do it in a long way...but... Thank you in advance. Kwankyu -- To post to this group, send email to sage

It's worse. Ctrl-C does not work if you try when you got sick of waiting. Kwankyu -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http

[sage-support] Inverse in lazy power series

Hi, Is it possible to compute in Sage a lazy power series y in x satisfying y = x/(1-y) ? I know a recursive definition is possible in Sage lazy power series module. What about the inverse 1/(1-y)? Thank you in advance. Kwankyu -- To post to this group, send email to sage-support
