GiANT logoGiANT:  Graphical Algebraic Number Theory

GiANT is a graphical interface for working with number fields. It is written in Java 1.4 and runs on top of the computer algebra system KASH 2.5.

Algorithms for dedicated computer algebra systems have developed rapidly. Nevertheless, user interfaces for these feature-rich systems have traditionally focused on command-line interaction. GiANT is a graphical user interface for computer algebra. It dynamically creates interactive diagrams, typesets formulas, and supports drag-and-drop manipulation of elements and polynomials. The result is a visual workspace designed to support mathematical intuition and reduce cognitive load versus text-only algebra systems.

GiANT was introduced at the MP60 Number Theory Conference, Technical University of Berlin, 10 June 2005. GiANT was featured at Algebra and Computation 2005, Tokyo Metropolitan University, 16 November 2005.

GiANT should run on Java 1.4 or higher. It has been tested on Mac OS X and some pure UNIX flavors, but not so much on Windows. GiANT requires a working installation of KASH 2.5, which is free.

Future development
Future development will be driven by the community. Possibilities include:  generalize GiANT to function with a wider variety of computer algebra systems. See the concluding remarks in the paper for more ideas.
