Solitary wave and other solutions for nonlinear heat equations
- A. Nikitin, T. Barannyk
- Mathematics, Physics
- 2 March 2003
A number of explicit solutions for the heat equation with a polynomial non-linearity and for the Fisher equation is presented. An extended class of non-linear heat equations admitting solitary wave… Expand
Group Classification of Nonlinear Schrödinger Equations
- A. Nikitin, R. Popovych
- Mathematics, Physics
- 1 August 2001
We propose an approach to problems of group classification. By using this approach, we perform a complete group classification of nonlinear Schrödinger equations of the form iψt + Δψ + F(ψ, ψ*) = 0.

- 1 December 2006
Abstract A group classification of the generalized complex Ginzburg–Landau equations is presented. An approach to group classification of systems of reaction–diffusion equations with general… Expand
Kinematical invariance groups of the 3d Schrödinger equations with position dependent masses
- A. Nikitin
- Physics
- 31 August 2017
Kinematical invariance groups of the 3d Schrodinger equations with position dependent masses and arbitrary potentials are classified. All non-equivalent classes of such equations are presented… Expand
On the new invariance algebras and superalgebras of relativistic wave equations
- W. I. Fushchich, A. Nikitin
- Physics
- 21 February 1987
The authors show that any relativistic wave equations for a particle with mass m>0 and arbitrary spin s is invariant under the Lie algebra of the group GL(2s+1, C). The explicit form of basis… Expand
Extended Poincaré parasuperalgebra with central charges and invariant wave equations
- A. Nikitin, A. V. Galkin
- Physics
- 1 December 2000
We describe irreducible representations of the extended Poincare parasuperalgebra (PPSA) which includes an arbitrary number N of parasupercharges, n (n≤{N/2}) central charges and an internal symmetry… Expand
Construction and classification of indecomposable finite-dimensional representations of the homogeneous Galilei group
- J. Niederle, A. Nikitin
- Physics
- 1 October 2006
We discuss finite-dimensional representations of the homogeneous Galilei group which, when restricted to its subgroup SO(3), are decomposed to spin 0, 1/2 and 1 representations. In particular we… Expand
Systems of reaction diffusion equations and their symmetry properties
- A. Nikitin, Ron J. Wiltshire
- Mathematics
- 22 March 2001
A constructive algorithm is proposed for the investigation of symmetries of partial differential equations. The algorithm is used to present classical Lie symmetries of systems of two nonlinear… Expand
