Froissart doublets in Padé approximation in the case of polynomial noise
The authors present a new approach to simplify the so-called restricted Froissart problem by considering polynomial noise instead of a power series noise \(\varepsilon\sum^\infty_{k=0}c_kz^k\). Through this simplification of the noise representation, the relation between the zeros of the polynomial and the position of the Froissart doublets is analyzed. The numerical estimations match with the theoretical ones.
