Laguerre transform
From Encyclopedia of Mathematics
The integral transform
where is the Laguerre polynomial (cf. Laguerre polynomials) of degree . The inversion formula is
if the series converges. If is continuous, is piecewise continuous on and , , , then
If and are continuous, is piecewise continuous on and , , , then
If is piecewise continuous on and , , , then for
and for ,
Suppose that and are piecewise continuous on and that
Then
The generalized Laguerre transform is
where is the generalized Laguerre polynomial (see [4]).
