Zero counting for a class of univariate Pfaffian functions

We present a new procedure to count the number of real zeros of a class of univariate Pfaffian functions of order 1. The procedure is based on the construction of Sturm sequences for these functions and relies on an oracle for sign determination. In the particular case of E-polynomials, we design an...
