A GENERALISATION OF DESCARTES’ RULE OF SIGNS
Published online by Cambridge University Press: 24 January 2012
Abstract
A generalisation of Descartes’ rule of signs to other functions is derived and a bound for the number of positive zeros of a class of integral transforms is deduced from that. A more precise rule of signs is also discussed in the light of these results.
