摘要：
We use the Kempf-Lascoux-Weyman geometric technique to calculate the resolution of orbit closures of representations of Dynkin quivers with every vertex being source or sink. We use this resolution to derive the normality of such orbit closures. As a consequence, we obtain the normality of certain orbit closures of type E.
