Asymptotic behaviour of the entire functions
, with real
n is studied. It turns out that the Phragmén–Lindelöf indicator of such a function is always non-negative, unless f(z)=eaz. For a special choice of
n=
n2 with irrational
, the indicator is constant and f has completely regular growth in the sense of Levin and Pfluger. Similar functions of arbitrary order are also considered.
