On δ-normality

Monotone versions of δ-normality

According to Mack a space is countably paracompact if and only if its product with [0, 1] is δ-normal, i.e. any two disjoint closed sets, one of which is a regular Gδ-set, can be separated. In studying monotone versions of countable paracompactness, one is naturally led to consider various monotone versions of δ-normality. Such properties are the subject of this paper. We look at how these prop...

Inferences on the Generalized Variance under Normality

Generalized variance is applied for determination of dispersion in a multivariate population and is a successful measure for concentration of multivariate data. In this article, we consider constructing confidence interval and testing the hypotheses about generalized variance in a multivariate normal distribution and give a computational approach. Simulation studies are performed to compare thi...

Local Asymptotic Normality in δ-Neighborhoods of Standard Generalized Pareto Processes

De Haan and Pereira [1] provided models for spatial extremes in the case of stationarity, which depend on just one parameter β > 0 measuring tail dependence, and they proposed different estimators for this parameter. This framework was supplemented in [2] by establishing local asymptotic normality (LAN) of a corresponding point process of exceedances above a high multivariate threshold, yieldin...

On the normality of operators

In this paper we will investigate the normality in (WN) and (Y) classes.
