| May 8, 2017 at 11:01 | comment | added | user64494 | I prefer solid arguments supplied with codes and references over unbased words. @xzczd | |
| May 8, 2017 at 8:37 | comment | added | xzczd♦ | @user64494 Then I think LaplaceTransform, which is essentially a integration, plays exactly the role of that "condition". As to the i.c., the definition in the wiki page doesn't have any requirement for it, and I think the "problem" with i.c. does not contradict the definition: if the weak solution may not satisfy the equation in some "region", then why can't it be on the boundary? | |
| May 8, 2017 at 8:17 | comment | added | user64494 | Your statement about a weak solution is unbased. Up to en.wikipedia.org/wiki/Weak_solution , a weak solution must satisfy the condition after " then an integrable function u would be said to be a weak solution if" in the cited Wiki article. This condition is not verified by you. Also there are problems with IC. @xzczd: | |
