When $f(z)$ is given by a known power series expansion, it is possible to construct the power series expansion for $f(z; p) = e^{-pz}f(z)$. We define $p_{opt}$ to be ...

For a power series $f(z) = \sum^\infty_{k = 0} a_kz^k$ let $S_n(f)$ denote the maximum modulus of the zeros of the $n$th partial sum of $f$ and let $r_n(f)$ denote ...
