Abstract

In this paper, we compute Galois groups over the rationals associated with generalized Laguerre polynomials Ln(∝)(x) whose discriminants are rational squares, where n and α are integers. An explicit description of the integer pairs ((n,∝)for which the discriminant of Ln(∝)(x) is a rational square was recently obtained by the author in a joint work with Filaseta, Finch and Leidy. Among these pairs ((n,∝), we show that for 2≤n≤5, the associated Galois group of Ln(∝)(x) is always.
