چکیده
We make use of the representation theory of the innnite dimensional Lie algebras a 1 , b 1 and b sl 2 to derive explicit formulas relating Schur's P-functions to Schur's S-functions. R esum e Nous utilisons la th eorie des repr esentations des alg ebres de Lie de dimension innnie a 1 , b 1 et b sl 2 pour obtenir des formules explicites reliant les fonctions P de Schur aux fonctions S de Schur.

The structure of a pair of nilpotent Lie algebras
Assume that $(N,L)$, is a pair of finite dimensional nilpotent Lie algebras, in which $L$ is non-abelian and $N$ is an ideal in $L$ and also $mathcal{M}(N,L)$ is the Schur multiplier of the pair $(N,L)$. Motivated by characterization of the pairs $(N,L)$ of finite dimensional nilpotent Lie algebras by their Schur multipliers (Arabyani, et al. 2014) we prove some properties of a pair of nilpoten...
متن کاملBounds for the dimension of the $c$-nilpotent multiplier of a pair of Lie algebras
In this paper, we study the Neumann boundary value problem of a class of nonlinear divergence type diffusion equations. By a priori estimates, difference and variation techniques, we establish the existence and uniqueness of weak solutions of this problem.
متن کاملSchur Type Functions Associated with Polynomial Sequences of Binomial Type
We introduce a class of Schur type functions associated with polynomial sequences of binomial type. This can be regarded as a generalization of the ordinary Schur functions and the factorial Schur functions. This generalization satisfies some interesting expansion formulas, in which there is a curious duality. Moreover this class includes examples which are useful to describe the eigenvalues of...
متن کاملWeyl Orbit Characters and Schur Functions
For finite Lie algebras, it is shown that characters can be defined first for Weyl orbits and then for irreducible representations. For AN Lie algebras, weight multiplicities can then be calculated by only stating that characters are equivalent to Schur functions. This also means that to calculate characters there is no need to sum over Weyl groups. The compatibility with the Weyl character for...
متن کاملAn Multiplicity Rules and Schur Functions
In applications of Weyl character formula for AN Lie algebras, it can be shown that the followings are valid by the use of some properly chosen system of weights which we call fundamental weights. Characters can be attributed conveniently to Weyl orbits rather than representations. The classsical Schur function SN (x1, x2, .., xN ) of degree N can be defined to be character of the representatio...
