A generalized Bailey pair, which contains several special cases considered by Bailey (Proc. London Math. Soc. (2), 50, 421–435 (1949)), is derived and used to find a number of new Rogers-Ramanujan type identities. Consideration of associated
q-difference equations points to a connection with a mild extension of Gordon’s combinatorial generalization of the Rogers-Ramanujan
identities (Amer. J. Math., 83, 393–399 (1961)). This, in turn, allows the formulation of natural combinatorial interpretations of many of the identities
in Slater’s list (Proc. London Math. Soc. (2) 54, 147–167 (1952)), as well as the new identities presented here. A list of 26 new double sum–product Rogers-Ramanujan type
identities are included as an Appendix.

In a recent letter, new representations were proposed for the pair of sequences (,), as defined formally by Bailey in his famous lemma. Here we extend and prove this result, providing pairs (,) labelled by the Lie algebra AN – 1, two nonnegative integers and k and a partition , whose parts do not exceed N – 1. Our results give rise to what we call a higher level Bailey lemma. As an application it is shown how this lemma can be applied to yield general q-series identities, which generalize some well-known results of Andrews and Bressoud. 相似文献

Using new -functions recently introduced by Hatayama et al. and by (two of) the authors, we obtain an A version of the classical Bailey lemma. We apply our result, which is distinct from the A Bailey lemma of Milne and Lilly, to derive Rogers-Ramanujan-type identities for characters of the W algebra.

A Bailey Tree for Integrals 总被引:1,自引:0,他引:1
We introduce the notion of integral Bailey pairs. Using the single-variable elliptic beta integral, we construct an infinite binary tree of identities for elliptic hypergeometric integrals. Two particular sequences of identities are described explicitly. 相似文献

A multiparameter generalization of the Bailey pair is defined in such a way as to include as special cases all Bailey pairs considered by W.N. Bailey in his paper [Identities of the Rogers-Ramanujan type, Proc. London Math. Soc. (2) 50 (1949) 421-435]. This leads to the derivation of a number of elegant new Rogers-Ramanujan type identities. 相似文献

We present two general finite extensions for each of the two Rogers-Ramanujan identities. Of these one can be derived directly
from Watson’s transformation formula by specialization or through Bailey’s method, the second similar formula can be proved
either by using the first formula and the q-Gosper algorithm, or through the so-called Bailey lattice.

We establish a number of extensions of the well-poised Bailey lemma and elliptic well-poised Bailey lemma. As application we prove some new transformation formulae for basic and elliptic hyper-geometric series, and embed some recent identities of Andrews, Berkovich and Spiridonov in a well-poised Bailey tree. 相似文献

In this paper, we find by inverse technique two solutions of a system of linear equations which together serve as a sufficient
and necessary condition for well-poised Bailey chains. Using these two solutions, we establish a new well-poised Bailey chain,
two usual Bailey chains, and a well-poised extension of Bailey’s lemma. Their applications to q-series are also investigated.

We present several new families of Rogers-Ramanujan type identities related to the moduli 18 and 24. A few of the identities were found by either Ramanujan, Slater, or Dyson, but most are believed to be new. For one of these families, we discuss possible connections with Lie algebras. We also present two families of related false theta function identities. 相似文献

We construct classes of Bailey pairs where the exponent of q in αn is an indefinite quadratic form. As an application we obtain families of q-hypergeometric mock theta multisums. 相似文献

Let r be a real number and A a tridiagonal operator defined by Aej=ej−1+rjej+1, j=1,2,…, where {e1,e2,…} is the standard orthonormal basis for ?2(N). Such tridiagonal operators arise in Rogers-Ramanujan identities. In this paper, we study the numerical ranges of these tridiagonal operators and finite-dimensional tridiagonal matrices. In particular, when r=−1, the numerical range of the finite-dimensional tridiagonal matrix is the convex hull of two explicit ellipses. Applying the result, we obtain that the numerical range of the tridiagonal operator is the square

For p∈{3,4} and all p′>p, with p′ coprime to p, we obtain fermionic expressions for the combination χ
1,s
p,p′+q
Δ
χ
p−1,s
p,p′ of Virasoro (W
2) characters for various values of s, and particular choices of Δ. Equating these expressions with known product expressions, we obtain q-series identities which are akin to the Andrews–Gordon identities. For p=3, these identities were conjectured by Bytsko. For p=4, we obtain identities whose form is a variation on that of the p=3 cases. These identities appear to be new.
The case (p,p′)=(3,14) is particularly interesting because it relates not only to W
2, but also to W
3 characters, and offers W
3 analogues of the original Andrews–Gordon identities. Our fermionic expressions for these characters differ from those of
Andrews et al. which involve Gaussian polynomials.

We present a method for proving q-series identities by combinatorial telescoping, in the sense that one can transform a bijection or a classification of combinatorial objects into a telescoping relation. We shall illustrate this method by giving a combinatorial derivation of Watson's identity, which implies the Rogers-Ramanujan identities. 相似文献

Consider structures (Ω, k, Γ) where Ω is an algebraically closed field of characteristic zero, k is a subfield, and Γ is a subgroup of the multiplicative group of Ω. Certain pairs (k, Γ) have been singled out as Mann pairs in [4]. We give new examples of such Mann pairs, we axiomatize for each Mann pair (k, Γ) the first-order theory of (Ω, k, Γ) in a cleaner way than in [4], and, as the main result of the article, we characterize the subsets of Ω n that are definable in (Ω, k, Γ). 相似文献

An ordered pair (e, f) of idempotents of a regular semigroup is called a skew pair if ef is not idempotent whereas fe is idempotent. We have shown previously that there are four distinct types of skew pairs of idempotents. Here we investigate the ubiquity of such skew pairs in full transformation semigroups. 相似文献
