Resumen de The composition algebra and the composition monoid of the Kronecker quiver

Andrew Hubery

• The Kronecker quiver is considered, and the relations for the specialisation at of the generic composition algebra are given, as well as those for Reineke's composition monoid. As a corollary, it is deduced that the composition monoid is a proper factor of the specialisation of the composition algebra. A normal form is also obtained for the varieties occurring in the composition monoid in terms of Schur roots.
