AI 中文总结
该研究构造了特征2域上的一个10元秩6代数拟阵,其由非Fano拟阵与Fano拟阵的代数实现粘合而成,证明了该拟阵的对偶不是代数的,说明代数拟阵的对偶不必为代数的。
AI 中文摘要
我们给出一个例子,表明代数拟阵的对偶不必是代数的。该例子是特征2域上10个元素的秩6拟阵,它通过将非Fano拟阵的代数实现与Fano拟阵的实现粘合得到,利用Ingleton-Main引理可证明其对偶不是代数的。
英文摘要
We give an example showing that the dual of an algebraic matroid need not be algebraic. Our example is a matroid of rank 6 on 10 elements which is algebraic in characteristic 2. It is obtained by gluing an algebraic realization of the non-Fano matroid to a realization of the Fano matroid. Its dual is shown not to be algebraic using the Ingleton-Main lemma.
