| Nov 28, 2019 at 16:26 | comment | added | Michael Engelhardt | Being able to solve a special case is always a good first step. Just do it. See whether you notice any patterns that might be useful also in the more general case. There likely are - your problem clearly has some symmetries. | |
| Nov 28, 2019 at 15:55 | comment | added | reduced team | Thank you very much for your suggestion, I read about the Fourier method for constant coefficients system of pde, but probably the question I'm going to ask you is pretty stupid but I'm completely new to the field, I would like to know how knowing the algebra can help me to deal with the non constant coefficients case, even a good reference will be of great help! Thank you very much in advance! | |
| Nov 28, 2019 at 15:43 | comment | added | Piero D'Ancona | Consider first the constant coefficient case, use Fourier and convert the problem into an algebraic one. Once the algebra is clear it should be possible to understand what's going on | |
| Nov 28, 2019 at 14:26 | comment | added | reduced team | Yes the problem is that with the formula that I previous wrote for some reason I was getting matrices with just 1 row and 0 columns, but now everything is perfect, so thank you very much for your help, and sorry about my incompetence but is the first time I'm using this forum. Thank you again for the support! | |
| Nov 28, 2019 at 14:23 | comment | added | Martin Sleziak | Maybe I am missing something, but I do not actually see what is the difference between the formula in the linked picture and the formula which you have removed from the post (and I have now included it back). | |
