论文摘要
尽管矩阵理论和$ q $ - 宽阔的理论之间有许多相似之处,最值得注意的是,在隐态级别上,直接总和就存在实质性差异。 $ Q $ -Matroids的直接总和直到最近才在文献中引入。在此简短说明中,我们表明,代表$ Q $ -MATROID的直接总和可能无法代表。是否可以通过给定的$ Q $ -Matroids来表征直接总和的表示仍然是一个空旷的问题。
While there are many parallels between matroid theory and $q$-matroid theory, most notably on the level of cryptomorphisms, there are substantial differences when it comes to the direct sum. The direct sum of $q$-matroids has been introduced in the literature only recently. In this short note we show that the direct sum of representable $q$-matroids may not be representable. It remains an open question whether representability of the direct sum can be characterized by the given $q$-matroids.
