Abstract
Inghanz [4] improved a previous result of Wiener [10] on nonharmonic F ourier-series. Modifying his weight function we obtain optimal results improving several earlier theorems of Kahane [7], Castro and Zuazua [ 2] and of Jaffard Tucsnak, and Zuazua [5]. Then we apply these results to simultaneous observability problems. (C) Academie des Sciences/Els evier, Paris.
