| Feb 15, 2011 at 1:42 | comment | added | psyduck | I'll check out the "short course on operator semigroups" as you suggested. In the mean-time, I think I have found an answer to my quandary (on wikipedia embarrassingly). I can just write my solution as $\int e^{-\lambda t} \phi_\lambda \mu( d\lambda )$ where $\mu$ is the spectral measure. At least, I think this works (I'm a physicist ... we aren't normally taught things like this in our coursework--at least I never was--so we need to learn this as we go in research). In any case, thank you very much for your reply to my question. | |
