Point-invariant classes of the third order ordinary differential equations
Vera V. Dmitrieva
Point transformations of the 3-rd order ordinary differential equations are considered. Special classes of ordinary differential equations that are invariant under the general poin…

On a point symmetry analysis for generalized diffusion type equations
V. V. Dmitrieva, E. G. Neufeld, R. A. Sharipov +1
Generalized diffusion type equations are considered and point symmetry analysis is applied to them. The equations with extremal order point symmetry algebras are described. Some ol…

Complete normality conditions for the dynamical systems on Riemannian manifolds
A. Yu. Boldin, A. A. Bronnikov, V. V. Dmitrieva +1
New additional equations for the Newtonian dynamical systems on Riemannian manifolds are found. They supplement the previously found weak normality conditions up to the complete no…
