摘要

假设 f,gf,gdd 次齐次多项式,分别定义光滑超曲面 Xf=V(f)Pm1X_f = V(f)\subset \mathbb{P}^{m-1}Xg=V(g)Pn1X_g = V(g)\subset\mathbb{P}^{n-1}。那么和 f(x)+g(y)f(x)+g(y) 定义了一个光滑超曲面 X=V(f(x)+g(y))Pm+n1X=V(f(x)+g(y))\subset\mathbb{P}^{m+n-1},并带有 μd\mu_d 缩放 gg 变量的作用。受 Orlov 工作的启发,我们构造了在 [X/μd][X/\mu_d] 上凝聚层导出范畴的一个半正交分解,条件是 dmax{m,n}d\geq \mathrm{max}\{m,n\}
