I am looking for English translation of the following two papers by Polya:
[1] G. Polya, Bemerkung über die Integraldarstellung der Riemannschen $\xi$-Funktion, Acta Math. 48(1926), 305-317; reprinted in his Collected Papers, Vol. II, pp. 243–255.
[2] G. Polya, Über trigonometrische Integrale mit nur reellen Nullstellen, J. Reine Angew. Math. 158(1927), 6-18; reprinted in his Collected Papers, Vol. II, pp. 265–275.
Thanks a lot for the heads-up! Mike
My translation of [1] can be found here (or at https://thosgood.com/translations/ if the above link ever breaks).
