On nilpotent filiform Lie algebras of dimension eight

International Journal of Mathematics and Mathematical Sciences, 2003
The aim of this paper is to determine both the Zariski constructible set of characteristically nilpotent filiform Lie algebras g of dimension 8 and that of the set of nilpotent filiform Lie algebras whose group of automorphisms consists of unipotent ...

Natural Filtrations of Infinite-Dimensional Modular Contact Superalgebras

Journal of Applied Mathematics, 2014
The natural filtration of the infinite-dimensional contact superalgebra over an algebraic closed field of positive characteristic is proved to be invariant under automorphisms by characterizing ad-nilpotent elements and the subalgebras generated by ...

Almost automorphic derivative of an almost automorphic function

V. N. Karazin Kharkiv National University. Ser. Mathematics, Applied Mathematics and Mechanics, 2017
In this article are obtained conditions when the derivative of a continuous almost automorphic (an asymptotically almost automorphic, an almost periodic, an asymptotically almost periodic) function remains a continuous almost automorphic (an asymptotically almost automorphic, an almost periodic, an asymptotically almost periodic) function, respectively.

Classical R-Operators and Integrable Generalizations of Thirring Equations

Symmetry, Integrability and Geometry: Methods and Applications, 2008
We construct different integrable generalizations of the massive Thirring equations corresponding loop algebras g^σ in different gradings and associated ''triangular'' R-operators.

On Tensor Squares of Reducible Representations of Almost Simple Groups. II

Моделирование и анализ информационных систем, 2011
Almost simple {SM}_m -groups are considered. A group G is called {SM}_m -group if the tensor square of any irreducible representation is decomposed into the sum of all characters with multiplicities not greater than m.

The conjugacy problem for $\operatorname {Out}(F_3)$

Forum of Mathematics, Sigma
We present a solution to the conjugacy problem in the group of outer automorphisms of $F_3$ , a free group of rank 3. We distinguish according to several computable invariants, such as irreducibility, subgroups of polynomial growth and subgroups ...

Local Automorphisms and Local Superderivations of Model Filiform Lie Superalgebras

Journal of Mathematics
In this paper, we give the forms of local automorphisms (resp. superderivations) of model filiform Lie superalgebra Ln,m in the matrix version. Linear 2-local automorphisms (resp. superderivations) of Ln,m are also characterized.

Riemann surfaces with a quasi large abelian group of automorphisms

Le Matematiche, 2011
In this work we classify all Riemann surfaces having a quasi large abelian group of automorphisms, i.e. having an abelian group of automorphisms of order strictly bigger than 2(g−1), where g denotes the genus of the Riemann surface.

Composite reductions for Kripke models

Моделирование и анализ информационных систем, 2010
Kripke factor-model concept is investigated. It is shown, that every factor-model is representexl as a decomposition of several spexdal facctor-models, which groups of automorphisms are primes. Moreover, we show, that every finite group is isomorphic for
