分块矩阵的Cassini域及边界

Cassini’s Regions and Bounds of Partitioned Matrices

给出了分左阵的一类Ｃａｓｓｉｎｉ型谱包含域，讨论了相应的边界问题。所得结果推广及改进文「１」～「１２」的相应结果。

Some Cassinis regions of partitioned matrices were given,corresponding bound problems were discussed.These results improved and generalized corresponding results in [1]～[12].
