§10. Further topics<br />
In this secti<strong>on</strong> I want to list some <strong>of</strong> the topics which have attracted<br />
interest in the past, and which are areas <strong>of</strong> present research. The lists <strong>of</strong><br />
papers are <strong>on</strong>ly meant to be pointers: you should c<strong>on</strong>sult the references in<br />
the listed papers for more informati<strong>on</strong>.<br />
(1) Kac’s Theorem: for any quiver the dimensi<strong>on</strong> vectors <strong>of</strong> the<br />
indecomposables are the positive roots <strong>of</strong> the graph.<br />
