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 ‵gασ and the convective gασ 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).
