论文摘要
基本升降机是一般的分裂操作。二元γ的分裂不必是γ。本文发现，二进制γ的未成年人的基础升压是二元γ。我们还发现了一个二进制γ的禁忌，其单个元素共延迟是二元γ。
Elementary lift is a generalized splitting operation. Splitting of a binary gammoid need not be a gammoid. This paper finds forbidden minors for a binary gammoid whose elementary lift is a binary gammoid. We also find forbidden minors for a binary gammoid whose single element coextension is a binary gammoid.
