Positivity properties associated with linear differential operators
The determination of the influence exerted on the analytic character of a real function fεC<sup>∞</sup> by the signs of its derivatives is a problem of longstanding interest in classical analysis. Most investigations of the problem have centered on extending the well known theorem of S....
