对于颤振稳定表示的任意模空间，构造了模空间上紧化射影空间颤振的若干光滑变体。分析了该紧化的边界。推导了光滑模型贝蒂数的显式公式。在简单表示模的情况下，构造了光滑模型的显式单元分解。
For any moduli space of stable representations of quivers, certain smooth varieties, compactifying projective space fibrations over the moduli space, are constructed. The boundary of this compactification is analyzed. Explicit formulas for the Betti numbers of the smooth models are derived. In the case of moduli of simple representations, explicit cell decompositions of the smooth models are constructed.
