| Mar 26 at 4:57 | comment | added | Willie Wong | I don't think the question being asked makes sense. You are treating $u$ as an $L^2$ valued function, then you cannot plug $u$ into $f$, which has domain $\mathbb{R}$. Perhaps you meant to think about $u$ as a space-time function, and $f$ as really acting on the final output. But then it is not compatible with the form of the chain rule you are suggesting. (In fact, if the spatial domain is non-compact, and $f(0) \neq 0$, you don't even have $f(u)$ is an element of $L^2(0,T;L^2)$.) So I think the first thing is to for you to think about and specify what exactly is this object $f(u)$. | |
