Dilogarithm identities

AN Kirillov - Progress of theoretical physics supplement, 1995 - academic.oup.com
We study the dilogarithm identities from algebraic, analytic, asymptotic, K-theoretic,
combinatorial and representation-theoretic points of view. We prove that a lot of dilogarithm …

Combinatorial constructions of modules for infinite-dimensional Lie algebras, I. Principal subspace

G Georgiev - Journal of Pure and Applied Algebra, 1996 - Elsevier
This is the first of a series of papers studying combinatorial (with no “subtractions”) bases
and characters of standard modules for affine Lie algebras, as well as various subspaces …

Fermionic counting of RSOS states and Virasoro character formulas for the unitary minimal series M (v, v+ 1): Exact results

A Berkovich - Nuclear Physics B, 1994 - Elsevier
The Hilbert space of an RSOS model, introduced by Andrews, Baxter, and Forrester, can be
viewed as a space of sequences (paths){a 0, a 1,…, a L}, with a j-integers restricted by 1≤ …

Continued fractions and fermionic representations for characters of M(p,p′) minimal models

A Berkovich, BM McCoy - Letters in Mathematical Physics, 1996 - Springer

Spinon bases, Yangian symmetry and fermionic representations of Virasoro characters in conformal field theory

P Bouwknegt, AWW Ludwig, K Schoutens - Physics Letters B, 1994 - Elsevier
We study the description of the SU (2), level k= 1, Wess-Zumino-Witten conformal field
theory in terms of the modes of the spin-1 2 affine primary field φα. These are shown to …

Fermionic character sums and the corner transfer matrix

E Melzer - International Journal of Modern Physics A, 1994 - World Scientific
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 …

Rogers–Schur–Ramanujan Type Identities for the M(p,p′) Minimal Models of Conformal Field Theory

A Berkovich, BM McCoy, A Schilling - Communications in mathematical …, 1998 - Springer
We present and prove Rogers–Schur–Ramanujan (Bose/Fermi) type identities for the
Virasoro characters of the minimal model M (p, p′). The proof uses the continued fraction …

Phase transitions in the and U(1) clock models

G Sun, T Vekua, E Cobanera, G Ortiz - Physical Review B, 2019 - APS
Quantum phase transitions are studied in the nonchiral p-clock chain, and a new explicitly U
(1)-symmetric clock model, by monitoring the ground-state fidelity susceptibility. For p≥ 5 …

The Andrews–Gordon Identities and q-Multinomial Coefficients

SO Warnaar - Communications in mathematical physics, 1997 - Springer
We prove polynomial boson-fermion identities for the generating function of the number of
partitions of n of the form n=j=1^L-1jf_j, with f_1≦i-1, f_L-1≦i'-1 and f_j+f_j+1≦k. The …

S Ole Warnaar - Journal of statistical physics, 1996 - Springer
The problem of computing the one-dimensional configuration sums of the ABF model in
regime III is mapped onto the problem of evaluating the grandcanonical partition function of …
