Tropical Fano Schemes

Sara Lamboglia

摘要:

定义了射影簇$X\subseteq \mathbb P^n$的Fano模式$\F_d(X)$的热带形式$\F_d(\trop X)$,并证明了$\F_d(\trop X)$是包含在$\trop \Grp(d,n)$中的多面体复形的支集.在一般$\trop \F_d(X)\subseteq \F_d(\trop X)$,但我们构造线性空间$L$,使$\trop \F_1(X)\subsetneq \F_1(\trop X)$,并表明,对于复曲面品种$\trop \F_d(X)=\F_d(\trop X)$。

英文摘要:

We define a tropical version $\F_d(\trop X)$ of the Fano Scheme $\F_d(X)$ of a projective variety $X\subseteq \mathbb P^n$ and prove that $\F_d(\trop X)$ is the support of a polyhedral complex contained in $\trop \Grp(d,n)$. In general $\trop \F_d(X)\subseteq \F_d(\trop X)$ but we construct linear spaces $L$ such that $\trop \F_1(X)\subsetneq \F_1(\trop X)$ and show that for a toric variety $\trop \F_d(X)=\F_d(\trop X)$.
