The goal of this paper is to collect some known results on the monotonicity with respect to p of the best constants associated with Sobolev immersions of type W 1,p(Ω) ''''''''→ Lq (Ω) when q ∈ {1, p, ∞}. More precisely, letting we recall some monotonicity results related with the following functions when Ω ⊂ RD is a given open, bounded and convex set with smooth boundary.
