However, the first sentence is only a rough description that motivates the discussion. The actual examples given (starting the second sentence) does not depend on dimension. | |
| Jul 8, 2016 at 6:28 | comment | added | Delio Mugnolo | Sure, but I understood your answer as a statement about general properties of the wave equation. Now I see that you mean that dispersivity may hold. | |

| Jul 7, 2016 at 21:37 | comment | added | Delio Mugnolo | Nice comment, but I'm puzzled by point 3). In what sense is the support of the solutions growing over time? In fact, isn't the solution the overlapping of two travelling waves, each with support that is moving but not increasing in measure? | |
