Abstract We study and classify those tame irreducible elliptic quasi-simple Lie algebras which are simply laced and of rankl⩾3. The first step is to identify the core of such an algebra up to central isogeny by identifying the coordinates. When the type isDorEthe coordinates are Laurent polynomials in ν variables, while for typeAthe coordinates can be any quantum torus in ν variables. The next step is to study the universal central extension as well as the derivation algebra of the core. These… 
The alternative torus and the structure of elliptic quasi-simple Lie algebras of type ₂
We present the complete classification of the tame irreducible elliptic quasi-simple Lie algebras of type A2, and in particular, specialize on the case where the coordinates are not associative. Here
MODULES FOR THE CORE OF EXTENDED AFFINE LIE ALGEBRAS OF TYPE A1 WITH COORDINATES IN RANK 2 QUANTUM TORI
We construct a Lie algebra L from rank 3 quantum tori and show that it is isomorphic to the core of extended affine Lie algebras of type A 1 . Then we construct two classes - which turn out to be
A finite number of defining relations and a UCE theorem of the elliptic Lie algebras and superalgebras with rank $\geq 2$
In this paper, we give a finite number of defining relations satisfied by a finite number of generators for the elliptic Lie algebras and superalgebras gR with rank ≥ 2. Here the R’s denote the
Multiloop realization of extended affine Lie algebras and Lie tori
An important theorem in the theory of infinite dimensional Lie algebras states that any affine Kac-Moody algebra can be realized (that is to say constructed explicitly) using loop algebras. In this
Classical Lie Superalgebras Over Simple Associative Algebras
Over arbitrary fields of characteristic not equal to 2, we construct three families of simple Lie algebras and six families of simple Lie superalgebras of matrices with entries chosen from different
Double-loop algebras and the Fock space
The fermionic Fock space admits two different actions of the quantized enveloping algebra of $\hat\sln$> The first one is a q-deformation of the well-known level-one representation of the affine Lie
JORDAN ANALOGUE OF LAURENT POLYNOMIAL ALGEBRA
Quantum tori or the octonion torus as the non-commutative version or as the alternative but not associative version of the algebra of Laurent polynomials in several variables are considered in Lie
