Mechanics of Continuous Media in $({\bar{L}}_n,g)$-spaces. I. Introduction and mathematical tools

Basic notions and mathematical tools in continuum media mechanics are recalled. The notion of exponent of a covariant differential operator is introduced and on its basis the geometrical interpretation of the curvature and the torsion in $({\bar{L}}_n,g)$-spaces is considered. The Hodge (star) operator is generalized for $({\bar{L}}_n,g)$-spaces. The kinematic characteristics of a flow are outline in brief.
