Abstracts: | The transformation formulae for differential d–operators are obtained. Such operators can be found in two-dimensional and three-dimensional problems of the mathematical theory of plasticity and the mechanics of growing solids. These transformations are caused by in the course of varying in the coordinate systems in order to simplify the differential equations (in particular, in the theory of plasticity) and the differential constraints imposed on the growing surface known in mechanics of growing solids. In the paper, the transformation formulae are derived and the corresponding examples are considered and discussed.
