| Mar 15 at 2:13 | comment | added | Iosif Pinelis | @KatsanikJr : Yes, indeed. On the other hand, as shown by Christian Remling, this condition cannot be dropped. | |
| Mar 14 at 10:23 | comment | added | KatsanikJr | @IosifPinelis Thank you for the clarification Prof. Pinelis. So considering that the \| AB\|\le \|A\|\, \|B\| property holds only then this proof is strong . Am I correct ? | |
| Mar 12 at 17:36 | comment | added | Iosif Pinelis | @ChristianRemling : Thank you for your comments. Indeed, I thought this could only be true for operator matrix norms -- as your example now shows. | |
| Mar 12 at 14:48 | comment | added | Christian Remling | And the source mentioned by the OP does refer to this site: en.wikipedia.org/wiki/Matrix_exponential#The_exponential_map | |
| Mar 12 at 14:36 | comment | added | Christian Remling | At least according to the usage suggested here, a "matrix norm" is just a norm on the vector space of matrices; it need not satisfy $\| AB\|\le \|A\|\, \|B\|$: en.wikipedia.org/wiki/Matrix_norm | |
