| Oct 30, 2023 at 20:09 | comment | added | Carlo Beenakker | @FedericoPoloni --- I asked on meta.mathoverflow.net/q/5778/11260 (this discussion is probably better suited for Meta than here) | |
| Oct 30, 2023 at 16:00 | comment | added | Iosif Pinelis | @FedericoPoloni : I have never seen elsewhere that one can be affiliated with a thing (such as a paper), rather than with a group/organization of people; see e.g. thefreedictionary.com/affiliation | |
| Oct 30, 2023 at 15:50 | comment | added | Federico Poloni | @IosifPinelis In my reading, "disclose your affiliation" means "disclose that you are the author", i.e., your affiliation with the paper. "Affiliation" here is used as a synonym of "association", and it doesn't mean "your university/employer". If you disagree, we can ask for a confirmation on meta.mo that this is the case. I hope the purpose is clearer with this reading. | |
| Oct 30, 2023 at 15:17 | comment | added | Iosif Pinelis | @FedericoPoloni : I do not see there a rule saying that it is always necessary to mention that "you" are the author of a paper "you" mention in your message. I do see "you must disclose your affiliation" there, and frankly I do not understand the purpose of disclosing the affiliation by the author of the paper. | |
| Oct 30, 2023 at 14:17 | comment | added | Federico Poloni | @Mostafa Just to clarify, let me note that it is always necessary to mention that you are the author of a paper you mention in your messages, by the rules in mathoverflow.net/help/promotion . Thanks for complying! | |

| Oct 28, 2023 at 13:50 | comment | added | Mostafa - Free Palestine | @FedericoPoloni The aim of this question is merely to find some connections and applications for this work for making it applicable for publishing in a high rank journal. | |

| Oct 26, 2023 at 11:37 | comment | added | Nathaniel Johnston | The distance between a matrix and the closest diagonal matrix (usually measured in the trace norm in this context) comes up naturally in quantum information theory when trying to quantify "how coherent" a quantum state is. See arXiv:1551.01854, for example. | |
| Oct 26, 2023 at 9:20 | comment | added | Mostafa - Free Palestine | @Oxonon Nice! So do you think the mentioned theorem above, may have some application in statistics? As I'm not an expert in this subject, could you please give some references? | |
| Oct 25, 2023 at 22:02 | comment | added | Oxonon | The operator norm, since we would usually care about worst-case performance. | |
| Oct 25, 2023 at 19:18 | comment | added | Mostafa - Free Palestine | @Oxonon Which norms are used to measure the distance of covariance matrices? | |
| Oct 25, 2023 at 18:23 | comment | added | Oxonon | Statistics, and in particular diagonal approximations to covariance matrices. One might try to bound how much worse is a model based on the best diagonal matrix is than the full matrix model. But that's only if you consider statistics to be an area of mathematics ;). | |
