We introduce a fermionic formula associated with any quantum affine algebra U q (X N (r) . Guided by the interplay between corner transfer matrix and the Bethe ansatz in solvable lattice models, we study several aspects related to representation theory, most crucially, the crystal basis theory. They include one-dimensional sums over both finite and semi-infinite paths, spinon character formulae, Lepowsky—Primc type conjectural formula for vacuum string functions, dilogarithm identities, Q… 
T-systems and Y-systems in integrable systems
T- and Y-systems are ubiquitous structures in classical and quantum integrable systems. They are difference equations having a variety of aspects related to commuting transfer matrices in solvable
What the characters of irreducible subrepresentations of Jordan cells can tell us about LCFT
In this article, we review some aspects of logarithmic conformal field theories (LCFTs) which can be inferred from the characters of irreducible submodules of indecomposable modules. We will mainly
Finite-dimensional crystals B2,s for quantum affine algebras of type D(1)n
The Kirillov–Reshetikhin modules Wr,s are finite-dimensional representations of quantum affine algebras U’q labeled by a Dynkin node r of the affine Kac–Moody algebra $$\mathfrak{g}$$ and a positive
Cluster Algebras and Integrable Systems
Author(s): Williams, Harold | Advisor(s): Reshetikhin, Nicolai | Abstract: We present a series of results at the interface of cluster algebras and integrable systems, discussing various connections
A uniform model for Kirillov-Reshetikhin crystals. Extended abstract
We present a uniform construction of tensor products of one-column Kirillov-Reshetikhin (KR) crystals in all untwisted affine types, which uses a generalization of the Lakshmibai-Seshadri paths (in
FERMIONIC FORMULAS AND RIGGED CONFIGURATIONS UNDER REVIEW
We give a review of the current status of the X = M conjecture. Here X stands for the one-dimensional configuration sum and M for the corresponding fermionic formula. There are three main versions of
Quantum Q-Systems and Fermionic Sums—The Non-Simply Laced Case
In this paper, we seek to prove the equality of the $q$-graded fermionic sums conjectured by Hatayama et al. in its full generality, by extending the results of Di Francesco and Kedem to the
AFFINE CRYSTALS , MACDONALD POLYNOMIALS AND COMBINATORIAL MODELS EXTENDED
Crystals are colored directed graphs encoding information about Lie algebra representations. Kirillov-Reshetikhin (KR) crystals correspond to certain nitedimensional representations of a ne Lie
Part 4. $X=M$ Theorem: Fermionic Formulas and Rigged Configurations under Review
We give a review of the current status of the X=M conjecture. Here X stands for the one-dimensional configuration sum and M for the corresponding fermionic formula. There are three main versions of

FERMIONIC CHARACTER SUMS AND THE CORNER TRANSFER MATRIX
We present a "natural finitization" of the fermionic q-series (certain generalizations of the Rogers–Ramanujan sums) which were recently conjectured to be equal to Virasoro characters of the unitary
Fermionic Formulas for Level-Restricted Generalized Kostka Polynomials and Coset Branching Functions
Abstract: Level-restricted paths play an important rôle in crystal theory. They correspond to certain highest weight vectors of modules of quantum affine algebras. We show that the recently

We study a family of power series characterized by a system of recursion relations (Q-system) with a certain convergence property. We show that the coefficients of the series are expressed by the
Functional relations and analytic Bethe ansatz for twisted quantum affine algebras
Functional relations are proposed for transfer matrices of solvable vertex models associated with the twisted quantum affine algebras Uq(Xn( kappa )), where Xn( kappa )=An(2), Dn(2), E6(2) and D4(3).

We consider the analogue of the six-vertex model constructed from alternating spin n/2 and spin m/2 lines, where . We identify the transfer matrix and the space on which it acts in terms of the
