论文摘要
引入了整数多膜体的天然曲霉，以表明来自矩形的整数多甲状腺的简单结构可产生所有整数多膜状药物。正如我们说明的那样，天然的矩形可以使整数多肌瘤散发出更多的启示。我们专注于使用它们的碱基，电路和环状平面以及每个环状平坦和每个元素的等级的整数多膜体的表征；我们为已知特征提供了一些新的特征和见解。
The natural matroid of an integer polymatroid was introduced to show that a simple construction of integer polymatroids from matroids yields all integer polymatroids. As we illustrate, the natural matroid can shed much more light on integer polymatroids. We focus on characterizations of integer polymatroids using their bases, their circuits, and their cyclic flats along with the rank of each cyclic flat and each element; we offer some new characterizations and insights into known characterizations.
