A Unique Decomposition of Involutions of Handlebodies
نویسنده
چکیده
We consider a PL involution of an orientable, 3-dimensional handlebody for which each component of the fixed point set is 2-dimensional. The handlebody is uniquely equivariantly decomposed as a disk sum of handlebodies Mi such that if M,■ = A¡ X /, then h | M¡ is equivalent to (i) a X id,, where a is an involution of A, or to (Ü) ida X r, where r(t) = -t for allí s / = [-1,1].

Involutions of 3-dimensional Handlebodies
We study the orientation preserving involutions of the orientable 3-dimensional handlebody Hg, for any genus g. A complete classification of such involutions is given in terms of their fixed points.
متن کامل3-manifolds Built from Injective Handlebodies
This paper looks at a class of closed orientable 3-manifolds constructed from a gluing of three handlebodies, such that the inclusion of each handlebody is π1-injective. This construction is the generalisation to handlebodies of the condition for gluing three solid tori to produce non-Haken Seifert fibered 3-manifolds with infinite fundamental group. It is shown that there is an efficient algor...
متن کاملAbstract involutions of algebraic groups and of Kac–Moody groups
Based on the second author’s thesis [Hor08] in this article we provide a uniform treatment of abstract involutions of algebraic groups and of Kac–Moody groups using twin buildings, RGD systems, and twisted involutions of Coxeter groups. Notably we simultaneously generalize the double coset decompositions established in [Spr84], [HW93] for algebraic groups and in [KW92] for certain Kac–Moody gro...
متن کاملExamples of Irreducible Automorphisms of Handlebodies
Automorphisms of handlebodies arise naturally in the classification of automorphisms of three-manifolds. Among automorphisms of handlebodies, there are certain automorphisms called irreducible (or generic), which are analogues of pseudo-Anosov automorphisms of surfaces. We show that irreducible automorphisms of handlebodies exist and develop methods for constructing a range of examples.
متن کاملInvolution Matrices of Real Quaternions
An involution or anti-involution is a self-inverse linear mapping. In this paper, we will present two real quaternion matrices, one corresponding to a real quaternion involution and one corresponding to a real quaternion anti-involution. Moreover, properties and geometrical meanings of these matrices will be given as reflections in R^3.
