What is KANT/KASH?
KANT is a computer algebra system for sophisticated computations in algebraic number fields that has been developed under the project leadership of Prof. Dr. M. E. Pohst at Technische Universit├Ąt Berlin.

The KANT functions are accessible through a user-friendly shell named KASH (KAnt SHell) that is freely available.

Read more on the KANT/KASH Homepage!

Obtaining KANT/KASH
You can pick up the current release of KASH from our ftp server or from our download page. Most of the functionality of KASH is also available on the web using webkash.

Downloads of the KANT 4 SCSCP packages are available here.

A note on KASH3 and older versions of KASH
Many parts of KASH have been redesigned since the release of KASH 2.5. We must apologize that code written for KASH 2.x will not run under KASH3 without modifications. However, there still will be bug fixes and at least one more version of KASH 2.x which will be released in late 2005 or early 2006.

SCIEnce (Symbolic Computation Infrastructure for Europe)

The SCIEnce project brings together the developers of four powerful symbolic computation software packages (GAP, KANT, Maple and MuPAD) and a major symbolic computation research institute (RISC-Linx) supported by research groups expert in essential underpinning technologies, to unite the European community of researchers in, and users of, symbolic computation.

QaoS (Querying Algebraic Objects System)

QaoS is a database interface implemented under the aspect of establishing a common gateway via web-browsers and computer algebra systems. QaoS is designed to fulfill modern demands for accessing large amounts of pre-computed algebraic data, both comfortably and fast.

GiANT is a graphical interface for working with number fields. It dynamically provides the user with typeset information, diagrams, and drag-and-drop functionality. The result is a level of human-computer interaction which is difficult to achieve in a shell environment. GiANT is written in Java 1.4 and runs on top of the computer algebra system KASH 2.5.

GiANT can be obtained from the GiANT homepage.
