A Generalization of Laguerre Polynomials

SIAM Journal on Mathematical Analysis, 1993
The authors investigate orthogonal polynomials for the inner product \[ \langle p,q\rangle= \int_ 0^ \infty {x^ \alpha e^{-x}\over \Gamma(\alpha+1)} p(x)q(x) dx+Mp(0)q(0) + Np'(0) q'(0), \] thereby generalizing the Laguerre polynomials \((M=N=0)\) and Koornwinder's Laguerre-type polynomials \((N=0)\).

The Addition Formula for Laguerre Polynomials

SIAM Journal on Mathematical Analysis, 1977
Bateman’s addition formula for Laguerre polynomials of order zero is generalized to the case of order $\alpha > 0$. The result is obtained as a limit case of the addition formula for disk polynomials.

Integrals of Products of Laguerre Polynomials

SIAM Journal on Mathematical Analysis, 1975
If $L_n(x)$ is the nth Laguerre polynomial, let $A_{rst} (\alpha ) = \int _0^\infty e^{ - \alpha x} L_r (x)L_s (x)L_t (x)dx$. It has recently been shown that $A_{rst} (\alpha ) > 0$ for $\alpha \geqq 2,r,s,t = 0,1, \cdots $, while $( - 1)^{r + s + t} A_{rst} (\alpha ) \geqq 0$ for $0 0$ for $r \geqq t$. The complete conjecture has not yet been proved,

On series representation in laguerre polynomials

Complex Variables, Theory and Application: An International Journal, 1993
This paper concerns with the existence of singularities of the series \[ \sum^ \infty_{n=0} a_ n L^{(\alpha)}_ n(z)\quad (\alpha\neq - 1,-2,\ldots) \] on the boundary of the region of convergence under certain assumptions on the coefficients.
