论文摘要
在本文中,我们给出了gröbner粉丝和spepht理想的$i_λ$的状态多层。特别是,我们表明,分区的$i_λ$的状态多层$λ=(λ_1,\ ldots,λ_m)$始终是概括性的permutoheDron,并且仅当$λ_{i-1} =λ_i> 0 $ $ i $ i $ i $ i $ i时,它是(通常的)permutoheDron。
In this paper, we give the Gröbner fan and the state polytope of a Specht ideal $I_λ$ explicitly. In particular, we show that the state polytope of $I_λ$ for a partition $λ=(λ_1, \ldots, λ_m)$ is always a generalized permutohedron, and it is a (usual) permutohedron if and only if $λ_{i-1}=λ_i>0$ for some $i$.
