In this paper, the uniqueness of algebroidal functions in the unit disc is investigated. Suppose that W(z) and M(z) are v-valued and k-valued algebroidal functions in the unit disc, respectively. Let e^iθ be a b-cluster point of order co or order ρ(x) of the algebroidal function W(z) or M(z). It is shown that if -↑E(aj, W(z)) = -↑E(aj,M(z)) holds in the domain {|z| 〈 1}∩Ω(θ-δ,θ+δ), where b, aj (j = 1,…, 2v + 2k + 1) are complex constants, then W(z) = M(z). The same results are obtained for the case that e^iθ is a Borel point of order co or order ρ(x) of the algebroidal function W(z) or M(z). 相似文献

Second order nondifferentiable multiobjective fractional programming under generalized univex functions 下载免费PDF全文
In this paper, a new class of second order $(d,\rho,\eta,\theta)$-type 1 univex function is introduced. The Wolfe type second order dual problem (SFD) of the nondifferentiable multiobjective fractional programming problem (MFP) is considered, where the objective and constraint functions involved are directionally differentiable. Also the duality results under second order$(d,\rho,\eta,\theta)$-type 1 univex functions are established. 相似文献

We introduce a class of asymptotically unbiased estimators for the second order parameter in extreme value statistics. The estimators are constructed by means of an appropriately chosen linear combination of two simple, but biased, kernel estimators for the second order parameter. Asymptotic normality is proven under a third order condition on the tail behavior, some conditions on the kernel functions and for an intermediate number of upper order statistics. A specific member from the proposed class, obtained with power kernel functions, is derived and its finite sample behavior studied in a small simulation experiment. 相似文献
