The variational theory of perfect fluid with intrinsic hypermomentum in space-time with nonmetricity
O. V. Babourova, B. N. Frolov
The variational theory of the perfect fluid with an intrinsic hypermomentum is developed. The Lagrangian density of such fluid is stated and the equations of motion of the fluid an…

On a Harmonic Property of the Einstein Manifold Curvature
O. V. Babourova, B. N. Frolov
The harmonicity condition of the curvature 2-form of a pseudo- Riemannian manifold is formulated on the basis of annulment of this form by the de Rham-Lichnerowicz Laplacian. The f…

Peculiarities of Matter Motion in Metric-Affine Gravitational Theory
O. V. Babourova, B. N. Frolov, M. Yu. Koroliov
On the basis of the Lie derivative method in a metric-affine space-time it is shown that in the metric-affine gravitational theory the energy-momentum conservation law and therefor…
