The product of an involution and a skew-involution

Linear Algebra and its Applications, 2020
Abstract We give necessary and sufficient conditions for a matrix over a field to be the product of an involution ( A 2 = I ) and a skew-involution ( A 2 = − I ).

Involutions of nonirreducible 3-manifolds

open access: yesTopology and Its Applications, 1991
The paper is concerned with the problem of distinguishing the equivalence classes of involutions of a compact orientable 3-manifold M, each of whose summands in a prime decomposition is irreducible and has infinite first homology, by considering their ...

Involutions and Coninvolutions

Numerical Analysis and Applications, 2023
Summary: A review of the relatively little-known matrix class, called coninvolutions, is given. The properties of these matrices are compared with those of the well studied involutory matrices or, briefly, involutions.

Location by involution

First Canadian Conference on Computer and Robot Vision, 2004. Proceedings., 2004
In this paper, we propose an iterative method of 3D location of 2D parallelogram or 3D parallelepiped shapes by monocular vision from a single image. The method we propose assumes that the camera is calibrated and that the size of the polygonal object is known. The 3D location is obtained in the following way.

Classification of symplectic birational involutions of manifolds of OG10 type [PDF]

open access: yesMathematische Zeitschrift
We give a complete classification of symplectic birational involutions of manifolds of OG10 type. We approach this classification with three techniques—via involutions of the Leech lattice, via involutions of cubic fourfolds, and finally lattice ...

Rapidly Involuting Congenital Hemangioma with Fetal Involution

Pediatric Dermatology, 2014
AbstractUncommon congenital hemangiomas differ from common infantile hemangiomas in their appearance, postnatal behavior, histopathology, and immunohistologic staining. Two types are well described in the literature: noninvoluting congenital hemangioma (NICH) and rapidly involuting congenital hemangioma (RICH).
