V. A. Kolmykov Voronezh State University
Abstract:
Forms generalizing Cartan–Tits and Kac–Moody forms are considered. Necessary conditions for these forms to be nonnegative are found.
Keywords:
Cartan–Tits form, Kac–Moody form, form with average diagonal dominance, nonnegative form, positive form, Coxeter graph.
