POLYCYCLIC RESTRICTED LIE ALGEBRAS

We define a polycyclic restricted Lie algebra to be the Lie analog of a polycyclic group, and we describe the structure of poly(cyclic or finite-dimensional) restricted Lie algebras. In particular, we prove that these are precisely the restricted Lie algebras whose restricted enveloping algebras have polynomial growth.

     

ON QUASI-TORAL RESTRICTED LIE ALGEBRAS

§1. IntroductionIn the theory of associative ring there are a number of known su?cient conditions forthe commutativity of an associative ring R, some in the form of a polynomial identity.For instance, it is a well-known result that if every element x of …

THE COHOMOLOGY OF MODULAR LIE ALGEBRAS WITH COEFFICIENTS IN A RESTRICTED VERMA MODULE

This paper determines the structure of the cohomology of a modular semisimple Lie algebra with coefficients in an arbitrary restricted Verma module.     

COMPLETE LIE ALGEBRAS WITH l-STEP NILPOTENT RADICALS

The authors first give a necessary and sufficient condition for some solvable Lie algebras with l-step nilpotent radicals to be complete, and then construct a new class of infinite dimensional complete Lie algebras by using the modules of simple Lie algebras. The quotient algebras of this new constructed Lie algebras are non-solvable complete Lie algebras with l-step nilpotent radicals.

LAX OPERATOR ALGEBRAS AND GRADINGS ON SEMI-SIMPLE LIE ALGEBRAS

A Lax operator algebra is constructed for an arbitrary semi-simple Lie algebra over ? equipped with a ?-grading, and arbitrary compact Riemann surface with marked points. In this set-up, a treatment of almost graded structures, and classification of the central extensions of Lax operator algebras are given. A relation to the earlier approach based on the Tyurin parameters is established.

AUTOMORPHISMS OF EXCEPTIONAL SIMPLE LIE ALGEBRAS

The scheme describing automorphisms of exceptional simple Lie algebras possessing geometrical realization over an algebraically closed field of characteristic p < 7 is proposed. In particular, automorphisms of Melikyan algebras g(m ₁, m ₂) (p = 5) and Skryabin algebras Y(m ₁, m ₂, m ₃) (p = 3) are found.     

DEGENERATIONS OF 7-DIMENSIONAL NILPOTENT LIE ALGEBRAS

ABSTRACT

We study the varieties of Lie algebra laws and their subvarieties of nilpotent Lie algebra laws. We classify all degenerations of (almost all) five-step and six-step nilpotent seven-dimensional complex Lie algebras. One of the main tools is the use of trivial and adjoint cohomology of these algebras. In addition, we give some new results on the varieties of complex Lie algebra laws in low dimension.
