KASH/KANT tutorial ================== Lesseni Sylla KANT is a sophisticated computer algebra system for computing in algebraic number fields, algebraic function fields and in local fields. It consists of a C-library of thousands of functions for doing arithmetic in these fields. Of course, the necessary auxiliaries from linear algebra over rings, especially lattices, are also included. The KANT functions are accessible through a user-friendly shell named KASH that is freely available. This shell enables the user to handle the number theoretical objects in the very same way as one would do using pencil and paper. In the courses, I will give an introduction to the KANT system and also we will see how to use the KANT system in several applications.
