From Totally Unimodular to Balanced 0, ±1 Matrices: A Family of Integer Polytopes
本文引入了一类整数多面体，并通过禁止子矩阵刻画其特征，其两个极端情形分别对应约束矩阵为全幺模和平衡矩阵，推广了Truemper-Chandrasekaran与Conforti-Cornuéjols的结果。
In this paper we introduce a family of integer polytopes and characterize them in terms of forbidden submatrices. The two extreme cases in this family arise when the constraint matrix is totally unimodular and balanced, respectively. This generalizes results of Truemper-Chandrasekaran and Conforti-Cornuéjols.
