In mathematics, in the area of combinatorics, a q-Pochhammer symbol, also called a q-shifted factorial, is a q-analog of the common Pochhammer symbol.The q-Pochhammer symbol is a major building block in the construction of q-analogs for instance, in the theory of basic hypergeometric series, it plays the role that the ordinary Pochhammer symbol plays in the theory of hypergeometric series.A q-series is a series in which the coefficients are functions of q, typically depending on q via q-Pochhammer symbols.
