In this paper we consider and solve the General Matrix Pencil Completion Problem (GMPCP) under single rank restrictions. These constraints are less limiting than any other restrictions on the GMPCP studied in the past. Thus, the obtained results directly generalize the existing results in the literature on the GMPCP. Finally, as one direct corollary of the main results, we obtain a novel result on determining the possible Kronecker invariants of a quasi-regular matrix pencil with a prescribed subpencil.

具有单秩限制的矩阵铅笔的完成

在本文中,我们考虑并解决了单秩限制下的一般矩阵铅笔完成问题 (GMPCP)。与过去研究的 GMPCP 的任何其他限制相比,这些限制的限制更少。因此,所获得的结果直接概括了 GMPCP 文献中的现有结果。最后,作为主要结果的一个直接推论,我们获得了一个关于确定具有指定子铅笔的准正则矩阵铅笔的可能 Kronecker 不变量的新结果。
