证明了在特征为0的代数闭域上的光滑射影簇上,半正则映射消除了对具有可扩法丛的局部完全交子簇的嵌入变形的所有阻碍.证明是基于L∞-代数理论和DG-格式的de Rham复形上的Tamarkin-Tsygan演算。
We prove that, on a smooth projective variety over an algebraically closed field of characteristic 0, the semiregularity map annihilates every obstruction to embedded deformations of a local complete intersection subvariety with extendable normal bundle. The proof is based on the theory of L∞-algebras and Tamarkin–Tsygan calculus on the de Rham complex of DG-schemes.
