چکیده
Let W a be an affine Weyl group. In 1987 Jian Yi Shi gave characterization of the elements w∈W in terms Φ + -tuples (k(w,α)) α∈Φ called vectors. Using these coefficients, formula is provided to compute standard length . this note we express twisted function coefficients.

Mullineux involution and twisted affine Lie algebras
We use Naito-Sagaki’s work [S. Naito & D. Sagaki, J. Algebra 245 (2001) 395–412, J. Algebra 251 (2002) 461–474] on LakshmibaiSeshadri paths fixed by diagram automorphisms to study the partitions fixed by Mullineux involution. We characterize the set of Mullineux-fixed partitions in terms of crystal graph of basic representations of twisted affine Lie algebras of type A (2) 2l and of type D (2) ...
متن کاملVertex Operators for Twisted Quantum Affine Algebras
We construct explicitly the q-vertex operators (intertwining operators) for the level one modules V (Λi) of the classical quantum affine algebras of twisted types using interacting bosons, where i = 0, 1 for A (2) 2n−1, i = 0 for D (3) 4 , i = 0, n for D (2) n+1, and i = n for A (2) 2n . A perfect crystal graph for D (3) 4 is constructed as a by-product.
متن کاملTwisted vertex representations of quantum affine algebras
Recent interests in quantum groups are stimulated by their marvelous relations with quantum Yang-Baxter equations, conformal field theory, invariants of links and knots, and q-hypergeometric series. Besides understanding the reason of the appearance of quantum groups in both mathematics and theoretical physics there is a natural problem of finding q-deformations or quantum analogues of known st...
متن کاملTwisted Yangians, Twisted Quantum Loop Algebras and Affine Hecke Algebras of Type Bc
We study twisted Yangians of type AIII which have appeared in the literature under the name of reflection algebras. They admit q-versions which are new twisted quantum loop algebras. We explain how these can be defined equivalently either via the reflection equation or as coideal subalgebras of Yangians of gln (resp. of quantum loop algebras of gln). The connection with affine Hecke algebras of...
