The aim of this paper is to prove new uncertainty inequalities of Heisenberg-type for a q-integral operator q with a bounded kernel. To do so, we prove a Nash and Carlson's inequalities for this transformation on q,1 ∩ q,p (Ω, |𝜔(x)|d q x) for 1 < p ≤ 2, on q,2 ∩ q,p (Ω, |𝜔(x)|d q x) for 1 < p < 2, and on q,p 1 ∩ q,p 2 (Ω, |𝜔(x)|d q x) for 1 < p 1 < p 2 ≤ 2. Our results can be applied to the the q-Fourier-cosine transform, the q-Dunkl transform, and the q-Bessel-Fourier transform.
