Résumé

The set $RT (M)$ of values of the $SL (2, ℂ)$ -Reidemeister torsion of a 3-manifold $M$ can be both finite and infinite. We prove that $RT (M)$ is a finite set if $M$ is the splice of two certain knots in the 3-sphere. The proof is based on an observation on the character varieties and $A$ -polynomials of knots.
