A Statistic on Involutions [PDF]
Journal of Algebraic Combinatorics, 2001 Given positive integers \(i< j\), the authors define an arc \([i, j]\) with span \(j-i-1\). An involution is a finite set of disjoint arcs. If \(i< k< j< l\), then \([i, j]\), \([k, l]\) are crossing arcs. \(I(n)\) denote the set of all involutions with arcs contained in \([n]\) (\(=\{1,2,\dots,n\}\)) and \(I(n, k)\) the set of involutions in \(I(n ...

Quaternion involutions and anti-involutions
Computers & Mathematics with Applications, 2007 The authors recall the definition of Hamilton's algebra of real quaternions. They define an involution of an algebra, without mentioning the structure where the involution takes place, and remark that the formal definition of an involution is not easy to find. Then an anti-involution is defined. Some calculations are added.

Human Thymic Involution and Aging in Humanized Mice
Frontiers in Immunology, 2020 Thymic involution is an important factor leading to the aging of the immune system. Most of what we know regarding thymic aging comes from mouse models, and the nature of the thymic aging process in humans remains largely unexplored due to the lack of a ...

∇-prime rings and their commutativity
Journal of Taibah University for Science, 2023 Consider a ring with an (anti)-automorphism ∇ of finite order. The fundamental aim of this manuscript is to introduce the notions of ∇-(semi)prime ideal and ∇-(semi)prime ring as a generalization of the notions of (semi)prime ideal, [Formula: see text ...

A Note on Soft Ideals and Soft Filters in Ternary Semigroups with Involution
Discussiones Mathematicae - General Algebra and Applications, 2020 The main purpose of this paper is to provide an effective content of theory of ternary semigroups with involution by applying soft set theory concepts. In this paper, we introduce some basic terms and definitions of different ideals in ternary semigroups

Australian and New Zealand Journal of Ophthalmology, 1986 AbstractInvolutional ptosis was corrected by either an anterior or posterior approach in 105 eyelids The posterior approach was preferred unless there was a specific indication for the anterior approach which included excess skin and bulky eyelids At operation approximately 10% of cases were found to have fatty degenerative changes in the anterior part

On the involution fixity of exceptional groups of Lie type [PDF]
, 2018 The involution fixity ${\rm ifix}(G)$ of a permutation group $G$ of degree $n$ is the maximum number of fixed points of an involution. In this paper we study the involution fixity of primitive almost simple exceptional groups of Lie type. We show that if
