(Rus- sian) This paper [of which part I appeared in Trudy Sem. Vektor. Tenzor. Analizu 2-3, SI-118 (1935)-', is a sv-- ternatic study of the invariants a-nd classification of-tri- vectors, together with the labyrinth of algebraic construc- tions necessary for their derivation. The atithor's main contributions-have been to give invariants characterizing the possible types of trivectors of rank 7 [the forms them- selves were given by Schouten, Rend. Circ. Mrt. Palermo ~5. 137-156 (1931)] and the 13 typcs and characteristL invariants for-rank 8 [C. R. (Doklady) Acad. Sci. URSS Y,, 353-356 (1935)1 in the field of complex numbers. The~%t present paper supplies proofs not originally given and cofl_!~i siderably simplifies cumbersome proofs in the earlier work of himself and others. A wealth of properties of trivectors and associated invariants and cornitants. is gNen. A start is also here made in the study of analogous problems for syni- metric trivalent-tensors, establishing inequaliti,_-s betwcen the analog6us invariants. L. C. Hutchinson. GUREVICH, G. B. 27571.

SOV/IZ4-58-3-3297 On the "Mechanical Analysis of Problems of Tectonics" (cont. ) 7. Textbooks of Recent Years. 8. On the So-called "Stress Hypothesis". Convincingly albeit too protractedly it is shown that gross distortions of the fundamental concepts of mechanics and errors committed in books on structural geology render the respective chapters worthless and unapplicable. Some considerations are presented concerning ways of utilizing the mechanics of a deformed body in the problems of tectonics. G.

However equaticns of type (1) bave no pbysical meaning. For example at dF-12 =const = V it. follows frcv (11 that for the dt instant t = 0 we have 612 = 0 and (~12 =,K'VI "e', the results that the stress occurs in the undeformed volume element. 'Equations of type (1) are su4table only for the description off attenuation such as is caused by the resistance of the surrounding medium, but does not follow from the defCrmation mec'banism itself. In a real body, the stresses are smaller (owing to their relaxation) than in an ideally vaustic medium. This is taken into account by the equations of B. DeryagiD (Zh. geofizi-kil, 1931, 1, 207; 1932, 2, 337), in which the 2 cemponents of stress are connected by a minus sign, which is equivalent to representing the strain in the form of a sum (and not a difference) of its elastic and inelastic c~-pponents. The author starts from the same concept, indicating that in the most general case it is characterized by the kncvn Maxwell relaxation equation, which can be supplPmented by an analysis of na-, c-nly the elastic (Hooke) and residual deforuiation. but also by t,h!g deformation of the elastic aftereffect.
