In this paper we study subalgebras of complex finite dimensional evolution alge-bras. We obtain the classification of nilpotent evolution algebras whose any subalgebra isan evolution subalgebra with a basis which can be extended to a natural basis of algebra.Moreover, we formulate three conjectures related to the description of such non-nilpotentalgebras.

In this paper, we study the properties of self-similar solutions of a cross-diffusion parabolic system. In particular, we find the Zeldovich–Barenblatt type solution to the cross diffusive system. The asymptotic behavior of self-similar solutions are analyzed for both the slow andfast diffusive regimes. It is shown that coefficients of the main term of the asymptotic of solution satisfy some system of nonlinear algebraicequations.

"Let E2 be the 2-dimensional Euclidean space, LSim(2) be the group of all linear simi- larities of E2 and LSim+(2) be the group of all orientation-preserving linear similarities of E2. The present paper is devoted to solutions of problems of global G-equivalence of paths and curves in E2 for the groups G =LSim(2), LSim+(2). Complete systems of global G-invariants of a path and a curve in E2 are obtained. Existence and uniqueness theorems are given. Evident forms of a path and a curve with the given global invariants are obtained."
