| May 8, 2015 at 19:37 | comment | added | Liviu Nicolaescu | For any sequence $t_n\searrow 0$ there exists a subsequence $(t_{n_k})$ such that $e^{t_{n_k} L} f\to f$ a.e. | |

| May 8, 2015 at 15:34 | comment | added | Robert Israel | Presumably it should be pointwise almost everywhere. | |
| May 8, 2015 at 15:28 | comment | added | Nate Eldredge | If $f \in L^2$ then $f$ is not well defined pointwise, so asking for pointwise convergence doesn't make sense. | |
| May 8, 2015 at 15:09 | comment | added | anonymous | @NateEldredge Apriori I would want $f \in L^2(\Omega)$, if such a result is possible. | |
| May 8, 2015 at 15:04 | comment | added | Nate Eldredge | What are you assuming about $f$? | |
