| Feb 22, 2016 at 12:50 | comment | added | user83150 | @Martin Thank you very much Martin! Indeed, I need to prove the convergence of the series $$ \sum_{p=0}^{\infty} \frac{x^{2p}}{(2p)!} A_p, $$ which resembles to your function $f(x)$. Then I need to see if I can obtain more information from your proposed equation. Thanks again! I'll be back soon! | |
| Feb 20, 2016 at 21:52 | comment | added | Martin Rubey | I just noticed (by computer) that $f(x) = \sum_{p,k} c_{p,k} t^k \frac{x^p}{p!}$ seems to satisfy $f'' - 3t f^2 + (2t-1)f = 0$. I have no idea whether that might be helpful, though. | |

More precise statement of the question, omitting the redundant explanations
