我们研究了在紧致黎曼曲面\(X\)上\(X\times \mathbb{P}^1\)上\(SU(2)\)等变全纯向量丛的高阶变形厄米-杨-米尔斯(dHYM)方程。对于一类涡旋型向量丛,我们建立了高阶dHYM方程解的存在性与一种称为\(Z\)-稳定性的代数几何稳定性概念之间的等价关系。我们表明\(Z\)-稳定性由\(D^{b}{\rm Coh}^{SU(2)}(X\times \mathbb{P}^1)\)中的布里奇兰德稳定性所蕴含,并且推测它们是等价的。
英文摘要
We study the higher rank deformed Hermitian-Yang-Mills (dHYM) equations for $SU(2)$-equivariant holomorphic vector bundles over $X\times \mathbb{P}^1$ for $X$ a compact Riemann surface. For a class of vector bundles of vortex type, we establish the equivalence between existence of solutions to higher rank dHYM equations and an appropriate notion of algebro-geometric stability, called $Z$-stability. We show that $Z$-stability is implied by, and conjecturally equivalent to, Bridgeland stability in $D^{b}{\rm Coh}^{SU(2)}(X\times \mathbb{P}^1)$.
