引入了P2上层的ags的模空间，并利用它们得到了P2上层的通常模空间的导范畴之间的函子。这些函子诱导的行动的shue代数的K-理论，我们重新解释重言式类。特别是，这个动作提供了[Bar 00]中Baranovsky算子的K理论版本。
We introduce moduli spaces of ags of sheaves on P 2 , and use them to obtain functors between the derived categories of the usual moduli spaces of sheaves on P 2 . These functors induce an action of the shue algebra on K-theory, which we reinterpret in terms of tautological classes. In particular, this action provides a K-theoretic version of Baranovsky’s operators from [Bar00].
