[sage-devel] Re: Experimental Gröbner Bases over Rin gs via Singular CVS
* Get the okay from Oliver Wienand the main author of the code. I think Oliver is reading this list. You have my okay and please ask if anything is unclear. At the moment I can only guarantee for the assumed correctness of the polynomial arithmetic, Gröbner basis and reduction (reduce, interred) over Z, Z/ m, Z/p^n. Other kernel commands may or may not work and may or may not give meaningful answers. But specially the arithmetic may have a few caveats, as I only really tested the operations for Gröbner basis. But having it in SAGE would help me a lot to better test the code. I also implemented a normal form algorithm for polynomial with respect to the ideal of polynomial defining a constant zero functions (without needing its Gröbner bases). The theory is mainly from Singmaster. And further an algorithm which explicitly constructs the bases without Buchberger or similar. I am not sure if this is of interest. ...

[sage-devel] Ginv 1.2. SPKG
Hi there, I made an SPKG for Ginv. http://wwwb.math.rwth-aachen.de/Janet/ginv.html Ginv is a small C++/Python package for computing involutive bases for polynomial and differential systems. Or in the words of the website: ginv implements the involutive basis algorithm by V. P. Gerdt and Y. A. Blinkov in C++. For a list of the main features, please see below. Moreover, the implemented computational methods are made accessible by ginv to a higher level programming language as a Python module. ginv is designed so as to be able to deal with polynomial systems, systems of differential equations, and finite difference schemes in the future. Some features of ginv (see Publications for more information): * Janet division and Janet-like division * implementation of several selection strategies for the involutive basis algorithm * 4 involutive criteria to avoid unnecessary reductions during involutive basis computations * Monomial orderings supported by ginv: degree reverse lexicographical, pure lexicographical, block orderings; their extensions to term over position and position over term orderings in the case of modules * Coefficient domains supported by ginv: rational numbers, integers, finite fields, algebraic extensions of the previous fields, transcendental extensions of the previous fields Note that this includes some rings (e.g. ZZ)! implementations of gcd algorithms for multivariate polynomials following W. S. Brown and R. Zippel I couldn't figure out yet how to call it.

I guess input definition blocks should be autonomous (not mixed with other code), so that it would be clear at what code position we already have the values probably the syntax could be just the same as in @interact just at least add new inputtype for textarea well, I can use usual (python) blocks to input data -- that seems not a big problem (but this is inconvenient (especially in matrix case)) I also know http://sagemath.blogspot.com/2008/02/mathematics-research-education-and-sage.html is there some sage-edu wishlist on http://sagetrac.org/sage_trac or somewhere? I think interact is just as useful in research as in education. So far I've used it several times in research; and, several times in education. It's great for both. The functionality you request above with textareas is something I definitely anticipated somebody else adding after the first version of interact. Good! The same with the spreadsheet-style input for matrices, which I would really like to see. Does anybody know of any good examples of javascript that inputs a spreadsheet or matrix of values?! and for the sake of interest: what (modules) should be considered to hack to implement input functionality To implement both functions you describe above you would probably only have to edit the file SAGE_ROOT/devel/sage/sage/server/notebook/interact.py This definitely won't be trivial, but fortunately that file has lots of documentation. You could probably get away with just modifying the input_box and InputBox classes to have an extra options that allows for a given number of rows and columns. Also, you might need some clever javascript or a submit button or something, to know when to submit the multiline input textarea. For the spreadsheet, it would depend if it uses much javascript or not. If it does, do something like the slider (and Slider) classes. If not, it will be more like InputBox. Happy coding!

Hi Chris, From foo.py, you should import the Sage libraries with import sage.all. If you don't want to use the libraries directly, and want a Sage process like you'd get if you were sitting down at the command-line, you can use sage0. For examples of how this is used, start up sage and run sage0?

[sage-devel] Sage 3.0.alpha1 released
Hello folks, here is Sage 3.0.alpha1. The bad news upfront: The gcc 4.3 compiler support didn't make it since the updated Singular SPKG is delayed due to some bugs. Martin Albrecht is working on it, so hopefully it will be in alpha2. We merged a massive number of tickets hours before alpha1 mostly thanks to Mike Hansen who did review a whole bunch of tickets. Other interesting bits: * the modabvar rewrite has been merged thanks to much work by William Stein, Craig Citro, Robert Bradshaw * much work for PolyBoRi, libSingular and Magma by Martin Albrecht * LinBox has been updated to the final 1.1.5 release thanks due to Clement Pernet * Many fixes and speedups to Elliptic curves, discrete log and various other bits by John Cremona * Carl Witty's new new randstate framework * A Tonelli-Shanks implementation by Steffan Reidt and Robert Bradshaw * Cython 0.9.6.13 has been merged thanks to Gary Furnish and Robert Bradshaw. This was a requirement to merge Gary's fast symbolics subsystem Sorry for anybody I did forget. It has been a wild merge session for the last twelve+ hours. What is most important: Overall weighted coverage score: 50.0% Total number of functions: 19290 w00t! Sources and binaries in the usual space. This build will be the basis of Bug Day 11 tomorrow.

What if I wanted to pass s (the Sage object) a string such as
diff(sin(x^2), x) ???
If you don't mind working with with strings, then you can use s.eval
which takes in a string and returns a string as well.
sage: s.eval('diff(sin(x^2),x)')
'2*x*cos(x^2)'
sage: s.eval('a = 2')
''
sage: s.eval('a')
'2'

Just to clarify this, by adding support for other languages, Kemeron means creating interfaces (or whatever) between Sage and languages such as Perl, Ruby, Scheme, etc., that are similar to the Sage interfaces to Magma, Mathematica, etc. In particular, this would make it so the notebook could be used with languages such as Ruby, Scheme, etc., which might be relevant to education, and would make it so rndom Ruby, Scheme, etc., code is usable in Sage programs. -- William --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-devel] Re: Hello
Hi Kemeron, The first place that you'll want to look is in sage/interfaces/ . This is the directory where all of the interfaces are kept. The file template.py is a template to start with when writing new interfaces. To get a rough working copy of a new interface, you pretty much just need to specify the command used to start the program and fill in some things like the prompt that Sage should look for, etc. --Mike On Fri, Apr 4, 2008 at 7:08 PM, Kemeron Siemens [EMAIL PROTECTED] wrote: Hi I'm Kemeron I am a student and I'm doing and independent study project with William involving Sage.

[sage-devel] Re: Sage 3.0.alpha1 released
On Apr 5, 2:35 am, mabshoff [EMAIL PROTECTED] dortmund.de wrote: Hello folks, here is Sage 3.0.alpha1. The bad news upfront: The gcc 4.3 compiler support didn't make it since the updated Singular SPKG is delayed due to some bugs. Martin Albrecht is working on it, so hopefully it will be in alpha2. We merged a massive number of tickets hours before alpha1 mostly thanks to Mike Hansen who did review a whole bunch of tickets. Other interesting bits: * the modabvar rewrite has been merged thanks to much work by William Stein, Craig Citro, Robert Bradshaw * much work for PolyBoRi, libSingular and Magma by Martin Albrecht * LinBox has been updated to the final 1.1.5 release thanks due to Clement Pernet * Many fixes and speedups to Elliptic curves, discrete log and various other bits by John Cremona * Carl Witty's new new randstate framework * A Tonelli-Shanks implementation by Steffan Reidt and Robert Bradshaw * Cython 0.9.6.13 has been merged thanks to Gary Furnish and Robert Bradshaw. This was a requirement to merge Gary's fast symbolics subsystem Sorry for anybody I did forget. It has been a wild merge session for the last twelve+ hours. What is most important: Overall weighted coverage score: 50.0% Total number of functions: 19290 w00t! Sources and binaries in the usual space. This build will be the basis of Bug Day 11 tomorrow. Sources: http://sage.math.washington.edu/home/mabshoff/release-cycles-3.0/sage... Binary: http://sage.math.washington.edu/home/mabshoff/release-cycles-3.0/sage... What is up next? * gcc 4.3 support * More of OSX 10.5 64 bit support * merges, merges, merges Cheers, Michael Ok, there is trouble in paradise: #2804: ssmod.py doctest failure - this is likely LinBox related. It happens only on occasion and I didn *never* hit in on 20+ full doctest runs on sage.math. Gary did hit it on his Dual QuadCore a couple times. #2802: inline_fortran.py doctest failure - we are unsure *what* caused it. It did pop up at some point and I didn't pay attention until a day later when I realized that it was reproducible. We suspect #2746 - any ideas Tim?
