Propagation of the invariance of germs of solutions of quasilinear differential equations with weighted derivativesThe paper contains various theorems on the propagation of the invariance of germs of solutions

On Boost-Invariant Solutions of Relativistic Field Equations structure of singular loci, are described. The notion of boost-invariant solutions, with the field functions

SOLITON-SOLUTIONS WITH NON-TRIVIAL HOPF INVARIANT ON AN INTERMEDIATE S3 MANIFOLDSOLITON-SOLUTIONS WITH NON-TRIVIAL HOPF INVARIANT ON AN INTERMEDIATE S3 MANIFOLD

Twistor structures and boost-invariant solutions to field equations with every solution of the basic system of algebraic equations are presented. The notion of a boost-invariant

Research of the Equations of a Viscous Inhomogeneous Fluid in a Hele-Shaw Cell by Group Analysis Method is described. Invariants of operators are found and invariant solutions of the equations are obtained

Exact self-consistent plane-symmetric solutions of the spinor-field equation with a nonlinear term dependent on the invariant p2Exact self-consistent plane-symmetric solutions of the spinor-field equation with a nonlinear term

Action principle and weak invariants© 2019 The Authors A weak invariant associated with a master equation is characterized in such a

Application of the Discrete Geometrical Invariants to the Quantitative Monitoring of the Electrochemical BackgroundThe statistics of the fractional moments (SFM) and discrete geometrical sets/invariants (DGI) were

Self-gravitating three-dimensional solitons in nonlinear scale-invariant electrodynamics space any gauge-invariant electrodynamic theory does not admit regular solutions. Supposing the gauge

KCC-invariants-based geometrization of a theory of electromagnetic and spinor fields on the background of the Schwarzschild spacetime. The stability analysis in terms of the second invariant demonstrate the difference in the behavior of geodesics
