我们引入了多项式稳定性条件的概念,推广了三角范畴上的Bridgeland稳定性条件。我们构造并研究了任意正规射影簇的一族多项式稳定性条件。这一族既包括辛普森稳定条件,也包括大体积极限布里奇兰稳定条件。我们证明了与Donaldson-Thomas不变量相关的稳定对的PT/DT对应(由Pandharipande和Thomas猜想)可以理解为我们的多项式稳定性条件族中的一个墙。类似地,我们证明了一维扭轮的稳定对与不变量之间的关系(最近由同一作者证明)是一个跨越墙的公式。14F05、18E30;14J32、14D20、14N35
We introduce the notion of a polynomial stability condition, generalizing Bridgeland stability conditions on triangulated categories. We construct and study a family of polynomial stability conditions for any normal projective variety. This family includes both Simpson-stability and large volume limits of Bridgeland stability conditions. We show that the PT/DT‐correspondence relating stable pairs to Donaldson‐Thomas invariants (conjectured by Pandharipande and Thomas) can be understood as a wallcrossing in our family of polynomial stability conditions. Similarly, we show that the relation between stable pairs and invariants of one-dimensional torsion sheaves (proven recently by the same authors) is a wall-crossing formula. 14F05, 18E30; 14J32, 14D20, 14N35
