In mathematics, a Lie superalgebra is a kind of generalisation of a Lie algebra.
Lie superalgebras are important in theoretical physics where they are used to describe the mathematics of supersymmetry.

Lie Superalgebra Structure on Eigenfunctions and Jets of Resolvent's Kernel, near the Diagonal of an n-th Order Ordinary Differential Operator.
The stabilizer of this point in the coadjoint action inherits the structure of the Lie superalgebra and can be described as the direct sum of the jets of the kernel of the resolvent of, and the eigenfunctions of, the given differential operator.

The Yangian Y(g) of classical Lie Superalgebra g (or superYangian) is introduced as a specialization of quantization of the bisuperalgebra of currents g[u] with cosuperalgebra structure defined by rational r-matrix.
The Yangians of simple Lie algebras play the role of the dynamical symmetries in quantum field theories and are used in investigation of integrable models of quantum mechanics and statistical physics.
The Yangians of Lie superalgebras of A(m,n) type were described in [3] and its representations were described in [4].

A Lie (super)algebra can admit more than one grading, for example, the free Lie (super)algebra on $n$ generators admits a {\bf Z}$_2$-grading, but also admits the length of ``words'' as a grading, or a multigrading where the degree of $x_i$ is the $n$-tuple $(0,\dots,1,\dots,0)$ (1 on the $i$-th place).
If $\lie$ is a liebracket, these commutators are $\lie(i,i)=0$ for all $i>0$ (this follows directly from the (graded) skew-symmetry and the fact that $x(i)$ is even for $i>0$), $\lie(i,0)$ for $i=-n,\dots,-1$ and $\lie(0,i)$ for $i=0,\dots,m$ (this has been explained in one of the previous sections).
The most convenient way to implement this is by making a Lie (super)algebra generator a rtype of itself, algebra_generator, and assigning a set-element-function and a clear function to it, which take care of all the necessary actions.

It is further shown that the finite dimensional irreducible modules over a (not necessarily classical) finite dimensional complex Lie superalgebra form a complete set if and only if the even part of the Lie superalgebra is reductive and the universal enveloping superalgebra is semiprime.
Abstract: We construct $Z_{2}$-graded crystal bases for thequantized universal enveloping algebra of the Lie superalgebra osp(1,2r).
The invariant $k(\cal O)$ is in many cases, equal to the odd dimension of the orbit $G\cdot\cal O$ where $G$ is a Lie supergroup with Lie superalgebra ${\mathfrak g}$.

In the case of para-Fermi statistics these relations can be associated with the orthogonal Lie algebra B_n=so(2n+1); in the case of para-Bose statistics they are associated with the Lie superalgebra B(0n)=osp(12n).
In a previous paper, a mathematical definition of ``a generalized quantum statistics associated with a classical Lie algebra G'' was given, and a complete classification was obtained.
Just as in the Lie algebra case, this definition is closely related to a certain Z-grading of G. We give in this paper a complete classification of all generalized quantum statistics associated with the basic classical Lie superalgebras A(mn), B(mn), C(n) and D(mn).

 Lie superalgebra structures in H-center dot (g;g) -- from Mathematica Information Center
Abstract Let g=vect(M) be the Lie (super)algebra of vector fields on any connected (super)manifold M; let ldquo-rdquo be the change of parity functor, C i and H i the space of i-chains and i-cohomology.
The Nijenhuis bracket makes into a Lie superalgebra that can be interpreted as the centralizer of the exterior differential considered as a vector field on the supermanifold associated with the de Rham bundle on M. A similar bracket introduces structures of DG Lie superalgebra in L * and for any Lie superalgebra g.
We use a Mathematica-based package SuperLie (already proven useful in various problems) to explicitly describe the algebras l * for some simple finite dimensional Lie superalgebras g and their ldquorelativesrdquo - the nontrivial central extensions or derivation algebras of the considered simple ones.

Abstract: \font\frak=eufm10 \def\f#1{\hbox{\frak#1}} A quadratic Lie superalgebra is a Lie superalgebra ${\f g}={\f g}_{\bar 0}\oplus{\f g}_{\bar 1}$ with a non-degenerate, supersymmetric, even and ${\f g}$-invariant bilinear form $B$, $B$ is called an invariant scalar product of ${\f g}$.
In this paper, we study properties of the decomposition of a quadratic Lie superalgebra ${\f g}={\f g}_{\bar 0}\oplus{\f g}_{\bar 1}$ relative to a fixed Cartan subalgebra of ${\f g}_{\bar 0}$.
Finally, we give two characterizations of the basic classical Lie superalgebras among the quadratic Lie superalgebras.

Making use of a Howe duality involving the infinite-dimensional Lie superalgebra $\hgltwo$ and the finite-dimensional group $GL_l$ we derive a character formula for a certain class of irreducible quasi-finite representations of $\hgltwo$ in terms of hook Schur functions.
We use the reduction procedure of $\hgltwo$ to $\hat{gl}_{nn}$ to derive a character formula for a certain class of level 1 highest weight irreducible representations of $\hat{gl}_{nn}$, the affine Lie superalgebra associated to the finite-dimensional Lie superalgebra $gl_{nn}$.
We also show that the characters of all integrable level 1 highest weight irreducible $\hat{gl}_{mn}$-modules may be written as a sum of products of hook Schur functions.

It is known that the Alexander-Conway knot polynomial is the Kontsevich integral applied to weight systems coming from the Lie superalgebra $gl(11)$.
We show that the corresponding link invariant is related to the multi- variable Alexander polynomial $\Delta$.
Moreover, we show that Vassiliev invariants coming from any solvable Lie algebra (or Lie superalgebra) belong to the subalgebra generated this implies that the space of Vassiliev invariants coming from Lie superalgebras is strictly larger than from all Lie algebras with invariant inner product.
