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 Laplace invariants for equations with dominating third-order partial derivative and two independent variables© 2016, Pleiades Publishing, Ltd.Laplace invariants are constructed and the constitutive equations

A free-group valued invariant of free knotsThe aim of the present paper is to construct series of invariants of free knots (flat virtual knots

Left-invariant metrics on a tensor bundle of type (2,0) over a Lie groupIn this paper, vertical and horizontal lifts of left-invariant vector fields are constructed
