Line 1:
In [[mathematics]], '''Weisner's method''' is a method for finding [[generating function]]s for [[special function]]s using [[representation theory]] of [[Lie group]]s and [[Lie algebra]]s, introduced by {{harvtxt|Weisner|1955}}. It includes [[Truesdell's method]] as a special case, and is essentially the same as [[Rainville's method]].
{{blockquote|... Weisner's group-theoretic method ... is a technique with uses the differential recurrence relations of a family of special functions to construct a Lie algebra of differential operators (Lie derivatives), under the action of which the family is invariant. The Lie derivatives can be exponentiated to obtain an action of the associated Lie group and this group action yields the generating functions. {{harvtxt|Miller Jr.|1974}}}}
