**2023**, Yuri N. Radayev, “Two-Point Rotations in Geometry of Finite Deformations”, in Holm Altenbach, Suren Manuk Mkhitaryan, Vahram Hakobyan, Avetik Varazdat Sahakyan, editors, Solid Mechanics, Theory of Elasticity and Creep (Advanced Structured Materials), Cham: Springer, →ISBN, page 276: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).
