arXiv 2022年
作者: Gazoulis, Dimitrios Department of Mathematics and Applied Mathematics University of Crete Heraklion70013 Greece Institute of Applied and Computational Mathematics FORTH Crete Heraklion700 13 Greece
We will prove that solutions of the Allen-Cahn equations that satisfy the equipartition of the energy can be transformed into solutions of the Euler equations with constant pressure. As a consequence, we obtain De Gio... 详细信息

Asymptotic Normality of the Conditional Value-at-Risk based Pickands Estimator
arXiv
收藏 引用
arXiv 2024年
作者: Li, Yizhou Polak, Pawel Department of Applied Mathematics and Statistics Stony Brook University United States Institute for Advanced Computational Science Stony Brook University United States
The Pickands estimator for the extreme value index is beneficial due to its universal consistency, location, and scale invariance, which sets it apart from other types of estimators. However, similar to many extreme v... 详细信息
