给出了光滑射影三重上μ-半稳定无挠层的第三陈特征标和上同调群的维数的有效上界.我们还得到了μ-稳定向量丛的模空间维数的界。
We give effective upper bounds for the third Chern characters and the dimensions of the cohomology groups of μ-semistable torsion-free sheaves on a smooth projective threefold. We also obtain bounds for the dimension of the moduli spaces of μ-stable vector bundles.
