WebMay 13, 2024 · If we define $\Gamma (x)=\int_0^\infty t^ {x-1}e^ {-t}\,\mathrm {d}t$, then the log-convexity follows from Cauchy-Schwarz or Jensen's Inequality, as shown at the end of this answer. However, the Bohr-Mollerup Theorem guarantees that we get the same $\Gamma (x)$ assuming the standard recurrence and log-convexity. – robjohn ♦ May 15, … frank herbert\u0027s children of dune 2003
