Series multisection
In mathematics, series built from equally spaced terms of another series
In mathematics, a multisection of a power series is a new power series composed of equally spaced terms extracted unaltered from the original series. Formally, if one is given a power series
then its multisection is a power series of the form
where p, q are integers, with 0 ≤ p < q. Series multisection represents one of the common transformations of generating functions.
