Low-Order Preconditioning of High-Order Triangular Finite Elements

SIAM Journal of Scientific Computing, 2018
Summary: We propose a new formulation of a low-order elliptic preconditioner for high-order triangular elements. In the preconditioner, the nodes of the low-order finite element problem do not necessarily coincide with the high-order nodes. Instead, the two spaces are connected using least squares projection operators.

Recognition by the Product Element Orders

Bulletin of the Malaysian Mathematical Sciences Society, 2019
If \(G\) is a finite group one may hope to determine \(G\) up to isomorphisms using certain numerical invariants. Invariants like \(|G|\), the sum of orders of the elements of \(G\) and the product of orders of the elements of \(G\) were all considered and found insufficient for the purpose.

High‐order finite elements compared to low‐order mixed element formulations

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2012
AbstractHigh‐order finite elements are commonly compared with linear element formulations showing that, in terms of the relation between computational time and achievable accuracy, linear element formulations are inferior to high‐order elements. On the other hand, the finite element community follows the h‐version approach due to its simplicity in ...

Groups with given element orders

2014
В статье приводится обзор результатов и некоторых открытых проблем, связанных со струк- турой (как правило, бесконечных) периодических групп с заданным набором порядков элементов. Работа основана на докладе, представленном на конференции "Алгебра и логика: теория и при- ложения", посвящённой 80-летию В. П.Шункова (Красноярск, 21–27 июля 2013 г.)
