内容説明
This work is a survey of algorithms for computing special examples in the study of Grothendieck groups, quadratic forms and derived categories of finite-dimensional algebras. Open questions including Lie algebras, Bruhat orders and Coxeter groups are investigated with the aid of computer algebras.
