Abstract

This Chapter is devoted to trigonometric polynomials and series of the form

$$\sum {{C_v}} {e^{vxi}},\;or\;\sum {{C_v}\sin vx} ,\;or\;\sum {{C_v}\cos vx} ,$$

with the assumption that their coefficients C v , are positive and monotonic, e.g. for some p ≥ 0, they are p-monotone (C n ≥ 0, ∆C n ≤ 0, ... , (−1)pp C n ≥ 0).
