provided example of Laplacian Matrices
|
| Jul 27, 2019 at 17:44 | comment | added | Manfred Weis | @ToniMhax in definition 1.4 of the article an $e-matrix$ is defined as a matrix for which $e$ (the all ones vector) is an eigenvector, so it seems to me that the term $e-matrix$ isn't used for constant row-sum matrices. | |
| Jul 27, 2019 at 16:12 | comment | added | Toni Mhax | Yes i saw it here bkms.kms.or.kr/submission/Source/Download.php?FileDir=/201711/… | |
| Jul 27, 2019 at 15:56 | comment | added | Manfred Weis | @ToniMhax could you please provide further information about where I can find that name mentioned? | |
| Jul 27, 2019 at 15:44 | comment | added | Toni Mhax | I know $e$-matrices for constant raw sum. | |
| Jul 27, 2019 at 15:29 | comment | added | Manfred Weis | @kjetilbhalvorsen true, but not all of 'my' matrices are of that structure because $|a_{ij}|\le 1$ for doubly stochastic matrices, whereas no such restriction exists for 'my' matrices. Of course every zero linesum matrix can be scaled to satisfy $\max(|a_{ij})|\in \lbrace 0,1\rbrace$ | |

removed capitals in title

| Jul 27, 2019 at 13:34 | comment | added | kjetil b halvorsen | Note that if $S$ is doubly-stochastic, then $S-I$ is your matrix. Maybe useful? | |

added a naming suggestion
|
| Jul 26, 2019 at 3:37 | comment | added | Manfred Weis | That was not on intent, I had forgotten about my earlier question, but still I would appreciate a keyword for those kind of matrices or, if there isn't one in use, suggestions for such a name. | |
| Jul 25, 2019 at 23:15 | comment | added | Spencer Dembner | Oh, I did not. Thanks for the heads up | |
| Jul 25, 2019 at 23:12 | comment | added | Gerry Myerson | @Spencer, maybe you noticed that that question was posted by the user who has posted this one. | |
