| Feb 19, 2020 at 18:01 | comment | added | sharpe | I suspect that the order is greater than or equal to $2$. | |
| Feb 19, 2020 at 17:14 | comment | added | sharpe | @DenisSerre Thank you very much for your comment. For example, can you tell me the order for Neumann eigenfunctions on equilateral triangle? | |
| Feb 19, 2020 at 16:55 | comment | added | Denis Serre | To complete Michael's comment, the order of the singularity at a corner is explicit and depends only upon the angle of this corner. Its magnitude can be expressed as an integral, but this is not so much explicit. | |
