无法保证同时对角化的,因为A,B未必可对角化,只能保证A,B课同时上三角化

n阶方阵A, (kA)的伴随矩阵=(k的n-1次方)乘以 A的伴随阵,怎么证明? 伴随矩阵是它的每个元素的代数余子式组成的,而kA的代数余子式是A的代数余子式的每个元素乘以k,A的代数余子式是n-1阶 矩阵AB的积的行列式等于A行列式与B的行列式的积 即 |AB|=|A||B| 其中AB都是n阶方阵 | A 0||-E B|=[...

PageRank is a web page ranking technique that radically changed the concepts of quality and truth of information found on the Web. The method was developed by Sergey Brin and Larry Page while studying at Stanford University and is currently an important ingredient of Google search engine. The ma...
也一样，不用看。对于零特征值，我们要求它们对秩的贡献也一样。考虑到对应零特征值的k阶Jordan块的秩是k−1，我们可以得到rankAB=rankBA的一个比较啰嗦的充要条件：rankAB=rankBA当且仅当AB中零特征值的代数重数与几何重数之差，等于BA中零特征值的代数重数与几何重数之差。坐等大神给出更简洁的条件。注意...

This line was then crossed into Rankflox/flox mice to examine Brca1 deletion-induced tumorigenesis in the presence or ab- sence of RANK expression (Supplementary information, Figures S1A, S1B and S2). All mouse lines examined appeared to develop normal mammary glands at puberty. In 4-month-...
Objective To explore the rank of problems of rural doctors in China by severity based on literature analysis. Methods A total of 308 pieces of literature relevant with rural doctor were retrieved from CNKI. Through literature review,the regions,authors' affiliation level and concerned fields of the...
