The p-norm joint spectral radius is defined by a bounded collection of square matrices with complex entries and of the same size. In the present paper the author investigates the p-norm joint spectral radius for integers. The method introduced in this paper yields some basic formulas for these spectral radii. The approach used in this paper provides a simple proof of Berger-Wang's relation concerning the ∞-norm joint spectral radius. 相似文献

In this paper we will first prove that the nontrivial Lp solutions of the vector refinement equation exist if and only if the corresponding subdivision scheme with a suitable initial function converges in Lp without assumption of the stability of the solutions. Then we obtain a characterization of the convergence of the subdivision scheme in terms of the mask. This gives a complete answer to the existence of Lp solutions of the refinement equation and the convergence of the corresponding subdivision schemes. 相似文献

The relation between the critical radius and the particle size distribution for generalized Ostwald type ripening processes whereby the mass transfer coefficient is modelled by a power law was derived. The critical radius is determined by the growth rate, the mass transfer coefficient and the mass balance, and is independent of whether the limiting stationary growth regime has been obtained. 相似文献

INTRODUCTION A polydisperse precipitate produced by nuclea-tion in a metastable supersaturated solution is far from thermodynamic equilibrium, i.e. a state of minimal free energy. A decrease of free energy is accom-plished by a coarsening of the precipitate which es-sentially reduces the surface free energy with respect to the surrounding solution. The process is called Ostwald ripening and is a direct consequence of the Kelvin effect (Adamson and Gast, 1997), that is the higher solubi… 相似文献
