We characterise interpolating and sampling sequences for the spaces
of entire functions f such that $ f e^{-\phi}\in L^p(\C)$, $p\geq 1 $, where $\phi$ is
a subharmonic weight whose Laplacian is a doubling measure. The
results are expressed in terms of some densities adapted to the metric
induced by $\Delta\phi$. They generalise previous results by Seip for the case
$\phi(z)=|z|^2$, Berndtsson and Ortega-Cerdà and Ortega-Cerdà and Seip
for the case when $\Delta\phi$ is bounded above and below, and Lyubarskiĭ
and Seip for 1-homogeneous weights of the form $\phi(z)=|z|h(\arg z)$,
where h is a trigonometrically strictly convex function. 相似文献

We consider nonlinear interferometric devices based on opto-thermal bistability with localized absorption and show how the introduction of composite structures within the interferometer makes feasible its setting and resetting between stable outputs by applying positive light pulses on different parts of the bistable device. Experimental demonstration of all-optical flip-flop operation is reported for two interferometric configurations, one of them being extremely simple and well suited for parallel processing. 相似文献

We study interpolating sequences in the unit ball for A–pwith p > 0, the Banach space of holomorphic functions f with(1 – |z|2)p |f(z)| bounded. The finite unions of A–p-interpolatingsequences are characterized by a Carleson type condition. 相似文献

We study the zero-varieties of holomorphic functions in the unit ball satisfying the growth condition log |f(z)|≤c
fλ(|z|), where λ:(0,1)→ℝ+ is a positive increasing function. We obtain some sufficient conditions on an analytic variety to be defined by such a function.
Some results for the particular case λ(r)=log(e/(1−r)), corresponding to the classA
−∞, generalize those of B. Korenblum in one variable.

We show that a discrete sequence \(\Lambda \) of the unit disk is the union of n interpolating sequences for the Nevanlinna class \(\mathcal {N}\) if and only if the trace of \(\mathcal {N}\) on \(\Lambda \) coincides with the space of functions on \(\Lambda \) for which the divided differences of order \(n-1\) are uniformly controlled by a positive harmonic function. 相似文献

We give a necessary and sufficient density condition for a sequence {a
k}
k
in the unit disk ofC to be interpolating for the classA
−∞ of holomorphic functions with polynomial growth. The condition goes along the lines of those found by Seip for the analogous
problem in Bergman spaces of the disk and by Berenstein and Li for some weighted spaces of entire functions. The result complements
an earlier characterization given by Bruna and Pascuas.
