Timeline for Is the hypergeometric function ${}_1F_2(1;a,a+\frac12;-x^2)$ an elementary function? How about its positivity, monotonicity, and convexity in $x$?

| Jun 10, 2023 at 22:16 | comment | added | qifeng618 | When a is a positive integer, I can derive explicit and elementary expressions for ${}_1F_2\bigl(1;a,a+\frac12;x\bigr)$. What I want is the result for the case that the variable $a$ is not an integer. | |
