Representing and interpolating sequences on parabolic Bloch type spaces. (English) Zbl 1252.35011
Summary: Let $$H$$ be the upper half-space of the Euclidean space. The $$\alpha$$-parabolic Bloch type space $$\mathcal B_{\alpha }(\sigma )$$ on $$H$$ is the set of all solutions $$u$$ of the parabolic equation $$(\partial /\partial t + ( - \Delta _{x})^{\alpha })u = 0$$ with $$0 < \alpha \leq 1$$ which belong to $$C^{1}(H)$$ and have finite Bloch norm with weight $$t^{\sigma }$$. In this paper, we study representing and interpolating sequences on parabolic Bloch type spaces. In our paper [Hiroshima Math. J. 41, No. 1, 55–87 (2011; Zbl 1233.35199)], the reproducing formula on $$\mathcal B_{\alpha }(\sigma )$$ was given. A representing sequence gives a discrete version of the reproducing formula on $$\mathcal B_{\alpha }(\sigma )$$. Interpolating sequences are closely related to representing sequences, and such sequences are very interesting in their own right.
