Covariant construction of the symmetric energy-momentum tensor of vector and spinor fields in an orthogonal frame of referenceA covariant method is devised to construct the symmetric energy-momentum tensor for vector fields

Vacuum stress-energy tensor of a massive scalar field in a wormhole spacetimeThe vacuum average value of the stress-energy tensor of a massive scalar field with nonminimal

Exact self-consistent solutions to the interacting spinor and scalar field equations in Bianchi type-I space-time-momentum tensor, which reflects the structural features of the Lagrangian density utilized, is also provided

Exact self-consistent solutions to nonlinear spinor field equations in Bianchi type-I space-time the implementation of the spin-connection formalism together with particular choices of the spacetime metrics

On the matrix equation for a spin 2 particle in pseudo-Riemannian space-time (II). Separating the variables in spherical coordinates Method and the third projection of the total angular momentum; at this, the formalism of Wigner D-function is applied

Spinor representation of Maxwell's equationsSpinors are more special objects than tensor. Therefore possess more properties than the more

Effective metrics in the non-minimal Einstein-Yang-Mills-Higgs theory and analyse it in terms of effective (associated, color and color-acoustic) metrics. We use a formalism

A geometric approach to the Lagrangian and Hamiltonian formalism of electrodynamics and Hamiltonian formalisms. Hamiltonian formalism of field theory has the advantage over the Lagrangian, which

Isomorphisms of Formal Matrix Rings with Zero Trace Ideals© 2018, Pleiades Publishing, Ltd. We obtain explicit criteria for the isomorphism of formal matrix
