Under what conditions does the Mittag-Leffler function ${E_{\alpha ,1}}(z),(0 < \alpha < 1)$...

None of these functions have real zeroes, because they can be written as moment generating functions of certain random variables $Y_\alpha$. More precisely, for $0<\alpha <1$ $$E_{\alpha,1}(z)=\mathb …

Absolute convergence of logarithm of polynomial with positive coefficient ($\ln G(z) = \sum\...

Not a complete solution, only a remark: assume $G(z)$ has no zeroes in the closed unit disk. If the series for $G(z)$ has radius of convergence >1 the series for $\log(G(z)$ will converge absolutely i …
