Operator methods and Lagrange inversion: A unified approach to Lagrange
formulas
Abstract.
We present a general method of proving Lagrange inversion formulas and give
new proofs of the s-variable Lagrange-Good formula [13] and
the q-Lagrange formulas of Garsia [7],
Gessel [10],
Gessel
and Stanton
[11, 12] and the author
[18].
We also give some q-analogues of the Lagrange formula in several
variables.
