| Jul 17, 2023 at 4:17 | comment | added | Terry Tao | I think that the operation of applying the Laguerre heat operator (suitably normalized), as well as multiplying by $e^{-\varepsilon x}$ (which corresponds on the Laguerre transform side to some sort of spatially discrete diffusion process) preserves both types of non-negativity, and so a combination of both of these operations should give the desired approximation. Not quite skilled enough in parabolic PDE though to check everything properly. | |

| Jun 17, 2021 at 19:04 | comment | added | Plussoyeur | @AlexandreEremenko Good catch. As a French person I always use positive to mean $\geq 0$ though I try to use nonnegative to be less confusing and then I end up writing very confusing sentences... I am editing the post. Thanks a lot | |
| Jun 17, 2021 at 13:47 | comment | added | Willie Wong | @AlexandreEremenko considering the OP used both the phrases "positive" and "non-negative" in the post, I am inclined to guess the former. | |
| Jun 17, 2021 at 13:43 | comment | added | Alexandre Eremenko | What does it mean "positive" in this question: $>0$ or $\geq 0$? | |
