On the irreducibility of a certain class of Laguerre polynomials. (English) Zbl 1019.11006

J. Number Theory 100, No. 2, 229-250 (2003).
It is shown that almost all generalized Laguerre polynomials \(L_m^{(m)}\) are irreducible over the rationals. This implies, due to a result of R. Gow [J. Number Theory 31, 201-207 (1989; Zbl 0693.12009)], that for almost all even \(m\) the Galois group of these polynomials is the alternating group \(A_m\).
