Sommario/riassunto |
|
The aim of this book is to study harmonic maps, minimal and parallel mean curvature immersions in the presence of symmetry. In several instances, the latter permits reduction of the original elliptic variational problem to the qualitative study of certain ordinary differential equations: the authors' primary objective is to provide representative examples to illustrate these reduction methods and their associated analysis with geometric and topological applications. The material covered by the book displays a solid interplay involving geometry, analysis and topology: in particular, it includes a basic presentation of 1-cohomogeneous equivariant differential geometry and of the theory of harmonic maps between spheres. |

Sommario/riassunto |
|
Assumptions of inability and the perceived costs of employing disabled persons are two of the primary reasons why it has been impossible or difficult for many capable disabled persons to access work and to continue working. This book considers the South African legal framework that seeks to promote such access and critiques it with particular reference to the intersections of the rights to equality and access to social security. One of the primary arguments is the need for a more active conception of social security in which access to work for disabled persons is recognised as an integral component of promoting both social security and substantive equality. |
