Pak-Leong Cheung, Tuen Wai Ng, Jonathan Tsai, S. C. P. Yam

摘要:

对于具有独立同分布的随机多项式,(独立同分布)零点服从任何公共概率分布$μ$,其支撑包含在单位圆内,证明了它们的一阶和高阶导数零点的经验测度弱收敛于$μ$ a. s.(几乎必然)。这,特别是,完成了最近的工作Subramanian的一阶导数的情况下,$μ$被假定为非均匀的。同样的a.s.弱收敛也将显示为极坐标和Sz。Nagy的广义导数,在一些较弱的条件下.

英文摘要:

For random polynomials with i.i.d. (independent and identically distribu-ted) zeros following any common probability distribution $μ$ with support contained in the unit circle, the empirical measures of the zeros of their first and higher order derivatives will be proved to converge weakly to $μ$ a.s. (almost sure(ly)). This, in particular, completes a recent work of Subramanian on the first order derivative case where $μ$ was assumed to be non-uniform. The same a.s. weak convergence will also be shown for polar and Sz.-Nagy's generalized derivatives, on some mild conditions.
