The Alcove Path Model and Tableaux
The second author and Postnikov have recently constructed a simple combinatorial model for the characters of the irreducible representations of a complex semisimple Lie group, that is referred to as the alcove path model. In this paper we relate the alcove path model to the the semistandard Young tableaux in type A and the KashiwaraNakashima tableaux in type C. More explicitly, we construct bij...
متن کاملFe b 20 06 Alcove path and Nichols - Woronowicz model of K - theory on flag varieties Toshiaki
We give a model of the K-ring of the flag varieties in terms of a certain braided Hopf algebra called the Nichols-Woronowicz algebra. Our model is based on the construction of the path operators by C. Lenart and A. Postnikov.
متن کاملAlcove Path and Nichols-woronowicz Model of the Equivariant K-theory of Generalized Flag Varieties
Fomin and Kirillov initiated a line of research into the realization of the cohomology and K-theory of generalized flag varieties G/B as commutative subalgebras of certain noncommutative algebras. This approach has several advantages, which we discuss. This paper contains the most comprehensive result in a series of papers related to the mentioned line of research. More precisely, we give a mod...
