This approach has been formulated for many cases (the list may not be complete):Īlin Bostan, Shaoshi Chen, Frédéric Chyzak, Ziming Li.Ĭomplexity of Creative Telescoping for Bivariate Rational Functions. Telescopers, and in some applications, for instance when an integral has natural boundaries, only the telescoper is of interest. This is interesting because certificates tend to be much larger than In recent years, a reduction-based approach has become popular which has the feature that it can find a telescoper without also constructing the corresponding certificate. For given integrands and summands, c reative telescoping is amount to constructing linear operators of special kind, which are called telescopers. 3 Contribution to the problemĬreative telescoping is the method of choice for obtaining information about definite sums or integrals, which was popularized by Zeilberger in the early 1990s. For instance, it remains complicated to simply put a mathematical text on the web (in a non-graphical format), because the "web-standard" MathML for mathematics is still poorly supported. Moreover, different tools use different data formats, which are often not very compatible. At any rate, it is not straightforward to combine several tools, like including graphics or computer algebra output in a paper. Several of these tools, and in particular T E X/L A T E X, are quite user unfriendly. For instance, mathematical texts are usually written with T E X/L A T E X, computations are done with numerical computation software or computer algebra systems, and presentations are done using Power Point or directly from a Pdf file. 2 Importance of the problem Currently, in the fields of mathematics, physics and computer science, people use different tools for each task. A major challenge is to pro-vide a similar software for scientists, with more specific support for things like mathematical formulas, complex computations, presentations from a laptop and so on. While this package is due for an update to 2.1 Statement of the problem Ordinary users have the choice between several office suits, like Microsoft Office, Open Office, or Star Office, for common desktop tasks, like text editing, drawing pictures or data administration. 14:09:53 by Greg Troxel | Files touched by this commit (1) |Įditors/TeXmacs: Add comments about guile 21:36:51 by Thomas Klausner | Files touched by this commit (5) 21:12:27 by Adam Ciarcinski | Files touched by this commit (1798) | 13:38:00 by Thomas Klausner | Files touched by this commit (3952) *: Revbump packages that use Python at runtime without a PKGNAME prefix ( ) Updated to version: TeXmacs-1.99.13nb9ĬVS history: ( Expand) 13:19:02 by Nia Alarie | Files touched by this commit (524).( ) Updated to version: TeXmacs-1.99.13nb10.( ) Updated to version: TeXmacs-1.99.13nb11.( ) Updated to version: TeXmacs-1.99.13nb12.( ) Updated to version: TeXmacs-1.99.13nb13.( ) Updated to version: TeXmacs-1.99.13nb14.Technical drawing editor and a presentation mode.
