| Jul 31, 2018 at 13:13 | comment | added | Qfwfq | @timur: yes, it's very well possible I misunderstood a bit: I know essentially nothing about PDEs (nonlinear or otherwise)! :) | |

| Mar 4, 2015 at 6:26 | comment | added | Denis Serre | @Qfwfq. Right, Schroedinger's equation is linear, but the number of independent variables is $1+3N$ where $N$ is the number of particles (electrons, protons, neutrons, ...) In practice, it is untractable by numerical schemes. For this reason, one makes approximations (density functional, Hartree-Fock, Slatter and so on), which replace it by a non-linear equation in $1+3$ variables. | |
| Mar 3, 2015 at 21:09 | comment | added | Qfwfq | Re "Nowadays, the interesting PDEs are non-linear": what about Schroedinger's equation? If I'm not mistaken it's linear, isn't it? | |
| Jun 4, 2011 at 22:36 | comment | added | AFK | Thanks for these insights. Do you have a reference for question 3? Like a book in the spirit of the Petrowsky school you mentionned? | |
