Szolem Mandelbrojt Relations entre la convexité dans le complexe et le prolongement des propriétés dans le réel Annales de l'institut Fourier, 22 no. 4 (1972), p. 13-46, doi: 10.5802/aif.433 Article PDF | Reviews MR 49 #580 | Zbl 0252.30031 Résumé - Abstract Chapter I indicates the growth of $\omega $ and of the convex function $C$ in order that from $\log |F(z)| \le \pi |y| - \omega (|y|)$ $(y = {\rm Im}\ z)$, $\log |F(n)| \le -C(|n|)$ ($n$ any integer, $F$ entire function) follows that $\log |F(z)| \le \pi |y| - C(a|z|)$. Chapter II shows functional properties which are necessarily true all over $[-\pi ,\pi ]$ if they are supposed on a part of $[-\pi ,\pi ]$, provided the corresponding Fourier series is ``sufficiently" lacunary. Chapter III shows analogies between methods of II and those used in adherent series. Bibliography |
