A remark on the Alexandrov–Fenchel inequality
Wang, Xu (Journal article; Peer reviewed, 2018)In this article, we give a complex-geometric proof of the Alexandrov–Fenchel inequality without using toric compactifications. The idea is to use the Legendre transform and develop the Brascamp–Lieb proof of the Prékopa ... -
A framework for predicting the local stress-strain behaviors of additively manufactured multiphase alloys in the sequential layers
Liu, Siqi; Lin, Meichao; Wang, Xu; Fu, Yuequn; Ren, Xiaobo; Zhang, Zhiliang; He, Jianying (Peer reviewed; Journal article, 2022)The additive manufacturing (AM) process often results in non-uniform microstructure and different mechanical properties in sequential layers, impacting the overall performance of the AM-ed component. However, it is extremely ... -
Numerical Simulation and Modelling Convention of Unsteady Fluidelastic Forces of Tube Arrays
Zhang, Mingjie; Wang, Xu; Øiseth, Ole Andre (Peer reviewed; Journal article, 2021)This paper presents a numerical investigation on the unsteady fluidelastic forces of tube arrays. The key focus is on the consistency between the unsteady fluidelastic force model and the quasi-steady model for tube arrays ... -
Some results on the Hard Lefschetz Condition
Tomassini, Adriano; Wang, Xu (Journal article; Peer reviewed, 2018)We discuss the Hard Lefschetz Condition (HLC) on various cohomology groups and verify them for the Nakamura manifold of completely solvable type and the Kodaira-Thurston manifold. A general Demailly-Griffiths-Kähler identity ... -
Vertical-horizontal decomposition of Laplacians and cohomologies of manifolds with trivial tangent bundles
Rollenske, Sonke; Tomassini, Adriano; Wang, Xu (Journal article; Peer reviewed, 2019)In this paper, we obtain a vertical–horizontal decomposition formula of Laplacians on manifolds with a special foliation structure. Two Nomizu-type theorems for cohomologies of nilmanifolds follow as applications.
