# Inverse Series Relations, Formal Power Series
and Blodgett-Gessel's Type Binomial Identities

**Abstract.**
A pair of simple bivariate inverse series relations are used
by embedding machinery to produce several double summation
formulae on shifted factorials (or binomial coefficients),
including the evaluation due to Blodgett-Gessel [Amer. Math. Monthly
**99** (1992), E3376].
Their *q*-analogues are established in the second section.
Some generalized convolutions are presented through formal
power series manipulation.

The following version are available:
