Does the coframe geometry can serve as a unification scheme?
Yakov Itin
The coframe field model is known as a viable model for gravity. The principle problem is an interpretation of six additionaldegrees of freedom. We construct a general family of con…
The Cauchy Relations in Linear Elasticity Theory
Friedrich W. Hehl, Yakov Itin
In linear elasticity, we decompose the elasticity tensor into two irreducible pieces with 15 and 6 independent components, respectively. The {\it vanishing} of the piece with 6 ind…
Coframe energy-momentum current. Algebraic properties
Yakov Itin
The coframe (teleparallel) description of gravity is known as a viable alternative to GR. One of advantages of this model is the existence of a conserved energy-momentum current wi…
On the derivation of the equations of motion in theories of gravity
Shmuel Kaniel, Yakov Itin
The equations of motion of massive particles in GR are completely determined by the field equation. We utilize the particular form of Einstein's field equation and propose for the…
On the derivation of the equation of motion in a scalar model
Shmuel Kaniel, Yakov Itin
A new method for derivation of the equation of motion from the field equation is proposed. The problem of embedding the singularities in a field satisfying the field equations is d…
The generalized teleparallel structure
Yakov Itin
It is proposed to describe a teleparallel structure as a combination of a Riemannian and a symplectic structure. The correspondent invariance group is an intersection of the orthog…
