Brekke, Svein; Seip, Kristian Density theorems for sampling and interpolation in the Bargmann-Fock space. III. (English) Zbl 0789.30024 Math. Scand. 73, No. 1, 112-126 (1993). Let \(\Gamma=\{z_ j\}^ \infty_{j=1}\) be a sequence of distinct complex numbers and associate with it a “multiplicity function” \(\nu\colon \Gamma \to \mathbb{N}\). A sampling and interpolation problem is formulated for the Bargmann-Fock space of entire functions, involving the \(\nu(z_ j)-1\) first derivatives at each point \(z_ j \in \Gamma\). Assuming \(\displaystyle\sup_{z \in \Gamma} \nu(z)<\infty\), a complete description of such sampling and interpolation is given, based on a density concept of Beurling. The theorems obtained are natural extensions of the results of parts I and II of this series of papers [see K. Seip, J. Reine Angew. Math. 429, 91–106 (1992; Zbl 0745.46034); K. Seip and R. Wallstén, J. Reine Angew. Math. 429, 107–113 (1992; Zbl 0745.46033)].
