In the paper under review, the author investigates the asymptotic distribution of zeros of the partial sums of the family of entire functions defined by \[ G(z):=\int_0^1\mu (t) t^{\alpha-1}(1-t)^{\beta-1}e^{zt} dt, \] where \(\operatorname {Re} \alpha\), \(\operatorname {Re} \beta >0\), \(\mu\) is Riemann integrable on \([0,1]\), continuous at \(t=0,1\) and satisfies \(\mu (0)\mu (1)\neq 0\). In particular, the author demonstrates in this work that the limit curve of the collection of suitably normalized zeros of the partial sums is the same for the whole family of functions under consideration. The reviewer remarks that the computer generated graphs of the limit curves are truly impressive.
