摘要
1989年以来,多位国内外学者讨论过定义在集上的GCD矩阵和LCM矩阵,获得了一批成果.本文是将他们的研究推广到所谓GCD幂矩阵和LCM幂矩阵上,得到了这两类矩阵在GCD闭集上的结构定理、行列式的计算公式,特别是得出了LCM幂矩阵和GCD幂矩阵在GCD闭集上的逆矩阵的漂亮结果.
Since 1989, GCD and LCM matrices defined on sets have been studied by several scholars, a lot of results being obtained. In this paper we extended their studies to so called GCD and LCM power matrices. We presented the structure theorem and the formulas of computing the determinants of these matrices. Especially, we obtained the excellent results on the inversion of GCD and LCM power matrices on GCD closed sets. Many former conclusions are simply corollaries of this paper.
