The Pólya-Jensen criterion for the Riemann Hypothesis asserts that RH is equivalent to the hyperbolicity of certain Jensen polynomials for all degrees d ≥ 1 and all shifts n.
This criterion was used by GRIFFIN-ONO-ROLEN-ZAGIER in one of their recent paper: JENSEN POLYNOMIALS FOR THE RIEMANN ZETA FUNCTION AND OTHER SEQUENCES.
The original Pólya-Jensen criterion was published in German as:
G. Pólya, Über die algebraisch-funktionentheoretischen Untersuchungen von J. L. W. V. Jensen, Kgl. Danske Vid. Sel. Math.-Fys. Medd. 7 (1927), 3-33.
But I could not read German.
Where can we find a proof of the Pólya-Jensen criterion in English ? Does any other papers or text books or exposition also contain a proof ?
Thank you in advance.
