We were interested in what does it mean to successfully combine aesthetics with information. From our focus group sessions, we found that the participants’ views about appropriate uses, as well as the appropriate relationship between aesthetics and information, were de...

Characteristic functions are constructed for classes of infinitely differentiable functions defined on a half-line and for Paley-Wiener classes. A corresponding result is given for normal operators defined in Hilbert space.
