Given 0 < q < 1 and f ∈ C [0, 1], the Lupaş q-transform is defined by \begin{align*} \Lambda_q(f;x)=\prod_{k=0}^{\infty}\frac{1}{1+q^{k}x}\sum_{k=0}^{\infty} \frac{f(1-q^k)q^{k(k-1)/2}x^k}{(1-q)(1-q^2)\ldots(1-q^k)}, \quad x \geqslant 0. \end{align*} During the last decades, this transform has been investigated from a variety of angles, including its analytical, geometric features, and properties of its block functions along with their sums. As opposed to the available studies dealing with a fixed value of q, the present work is focused on the injectivity of Λq with respect to parameter q. More precisely, the conditions on f such that equality Λq (f ; x) = Λr (f ; x), x ⩾ 0 implies q = r have been established.enLupa¸s q-analogue of the Bernstein operatorsLupa¸s q-transformanalytic functionq-periodicity47B3830A9926C15Article
