${\rm PL}$ involutions of $S\sp{1}\times S\sp{1}\times S\sp{1}$

PL INVOLUTIONS ON THE NONORIENTABLE 2-SPHERE BUNDLE OVER Sx

We show that there are exactly nine distinct PL involutions on the nonorientable 2-sphere bundle over Sl, up to PL equivalences. This, together with results of [1], [3] and [8], classifies all PL involutions on the 2sphere bundles over S1.

Title of Report: a Ap Pp Pl Li Ic Ca at Ti Io on N P Pl La at Tf Fo or Rm M Table of Contents

This report explains the objectives and motivations of building the local evaluation platform. This platform is described in terms of hardware and software components, with a presentation of the machines, the networks that interconnect them (an ATM and an Ethernet LANs) and the software tools that run on it and which behaviour and performances have to be evaluated in the framework of automotive...

PL-Geodesics on PL-Continuous Partial Meshes

Geometric characteristics of 2-manifolds embedded in R space have been analyzed from the point of view of differential geometry and topology. In the past, results relevant to these areas have been found for C curves and surfaces. However, current scientific, industrial, entertainment and medical applications, and availability of more powerful point sampling systems, press for characterization o...

Pfister Involutions

The question of the existence of an analogue, in the framework of central simple algebras with involution, of the notion of Pfister form is raised. In particular, algebras with orthogonal involution which split as a tensor product of quaternion algebras with involution are studied. It is proven that, up to degree 16, over any extension over which the algebra splits, the involution is adjoint to...
