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 consider two linearly coupled masses, where one mass can have inelastic impacts with a fixed, rigid stop. This leads to the study of a two degree of freedom, piecewise linear, frictionless, unforced, constrained mechanical system. The system is governed by three types of dynamics: coupled harmonic oscillation, simple harmonic motion and discrete rebounds. Energy is dissipated discontinuously in discrete amounts, through impacts with the stop. We prove the existence of a non-zero measure set of orbits that lead to infinite impacts with the stop in a finite time. We show how to modify the mathematical model so that forward existence and uniqueness of solutions for all time is guaranteed. Existence of hybrid periodic orbits is shown. A geometrical interpretation of the dynamics based on action coordinates is used to visualize numerical simulation results for the asymptotic dynamics. 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.

A quantum mechanical perturbed stationary state study of the collinear collision of two identical diatomic molecules within the normal mode decomposition technique is presented. Various collision systems are investigated and are classified in three different groups according to their dynamical behaviour. 相似文献

In a very rough experiment using two MgO plates, coated with a 200 Å thick YBaCuO film to increase their reflectivity, and facing each other their YBaCuO films to make a Perot-Fabry (PF) interferometer, we have observed a 43% maximum transmission and a finesse around 33 at v=29 cm–1, in good accordance with a new phenomenological model for YBaCuO. Much higher performances can be expected by optimizing the YBaCuO film thickness. 相似文献
