Given a sequence $\{x_n\}^\infty_{n=0}$ in a Banach space, it is well known that if there is a sequence $\{t_n\}^\infty_{n=0}$ such that $\|x_{n+1} - x_n\| \leqslant ...
This paper presents new asymptotics on the coefficients of Æ’(x) expanded in forms of ultraspherical or Jacobi polynomial series, which imply the rate of the decay of ...
