A characterization of the exponential function and Lindelöf function (Q1088811)

The author has earlier considered entire functions f(z) with only negative zeros (if any). Conditions were given implying that \(f(z)=e^{p(z)}\), p(z) polynomial. In this paper the zeros are located in a sector. But now most conditions are too complicated to be of interest, further investigation might give more significant results.
