Abstract
In this work, we introduce a family of weighted Bergman spaces \(\{{\mathcal {A}}_{\alpha ,n}\}_{n\in {\mathbb {N}}}\). This family satisfies the continuous inclusions \({\mathcal {A}}_{\alpha ,n}\subset \cdots \subset {\mathcal {A}}_{\alpha ,2}\subset {\mathcal {A}}_{\alpha ,1}\subset {\mathcal {A}}_{\alpha ,0}={\mathcal {A}}_{\alpha }\), where \({\mathcal {A}}_{\alpha }\) is the classical weighted Bergman space. Next, we define and study the derivative operator \(\nabla =\frac{\text{ d }}{\text{ d }z}\) and its adjoint operator \(L_{\alpha }=z^2\frac{\text{ d }}{\text{ d }z}+(\alpha +2) z\) on the weighted Bergman space \({\mathcal {A}}_{\alpha }\), and we establish an uncertainty inequality of Heisenberg-type for this space. A more general uncertainty inequality for the space \({\mathcal {A}}_{\alpha ,n}\) is also given when we considered the operators \(\nabla _n=\nabla ^n\) and \(L_{\alpha ,n}:=(L_{\alpha })^n\). Afterward, we give Heisenberg-type and Laeng-Morpurgo-type uncertainty inequalities for the Bargmann transform \(B_{\alpha }\), which is an isometric isomorphism between the space \({\mathcal {A}}_{\alpha }\) and the Lebesgue space \(L^2({\mathbb {R}}_+,\text{ d }\mu _{\alpha })\), where \(\text{ d }\mu _{\alpha }\) is an appropriate measure.
