  Since deformation manifests itself as a change in the metric characteristics of continuum, in the theory of finite deformations, it is then necessary to compare the referential ‵g_ασ and the convective g_ασ metrics. We systematically employ Latin indices in order to refer to spatial components of geometrical objects, whereas Greek indices to point on convective components (only a few instances can be found in the present study) or referential components (additionally, root symbol is sometimes supplied by backprime).
