Abstract

This paper provides the connection between the Hankel transform and aerating transforms of a given integer sequence. Results obtained are used to establish a completely different Hankel transform evaluation of the series reversion of a certain rational function Q(x)Q(x) and shifted sequences, recently published in our paper \cite{part1}. For that purpose, we needed to evaluate the Hankel transforms of the sequences \seqnα2CnβCn+1\seqn{\alpha^2 C_n-\beta C_{n+1}} and \seqnα2Cn+1βCn+2\seqn{\alpha^2 C_{n+1}-\beta C_{n+2}}, where C=\seqnCnC=\seqn{C_n} is the well-known sequence of Catalan numbers. This generalizes the results of Cvetkovi\' c, Rajkovi\'c and Ivkovi\'c \cite{CRI}. Also, we need the evaluation of Hankel-like determinants whose entries are Catalan numbers CnC_n and which is based on the recent results of Krattenthaler \cite{krattCat}. The results obtained are general and can be applied to many other Hankel transform evaluations.
