Erdős‐Rogers Functions for Arbitrary Pairs of Graphs

open access: yesRandom Structures &Algorithms, Volume 68, Issue 3, May 2026.
ABSTRACT Let fF,G(n)$$ {f}_{F,G}(n) $$ be the largest size of an induced F$$ F $$‐free subgraph that every n$$ n $$‐vertex G$$ G $$‐free graph is guaranteed to contain. We prove that for any triangle‐free graph F$$ F $$, fF,K3(n)=fK2,K3(n)1+o(1)=n12+o(1).$$ {f}_{F,{K}_3}(n)={f}_{K_2,{K}_3}{(n)}^{1+o(1)}={n}^{\frac{1}{2}+o(1)}. $$Along the way we give a

Modular Identities and Explicit Evaluations of a Continued Fraction of Ramanujan

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2012, Issue 1, 2012., 2012
We study a new continued fraction of Ramanujan. We prove its modular identities and give some explicit evaluations.

Generalisations of Capparelli's and Primc's identities, II: Perfect An−1(1)$A_{n-1}^{(1)}$ crystals and explicit character formulae

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract In the first paper of this series, we gave infinite families of coloured partition identities which generalise Primc's and Capparelli's classical identities. In this second paper, we study the representation theoretic consequences of our combinatorial results.

A Parameter for Ramanujan′s Function χ(q): Its Explicit Values and Applications

open access: yesInternational Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
We define a new parameter Ik,n involving quotient of Ramanujan′s function χ(q) for positive real numbers k and n and study its several properties. We prove some general theorems for the explicit evaluations of the parameter Ik,n and find many explicit values.

Certain Transformation Formulae for Polybasic Hypergeometric Series

open access: yesInternational Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
Making use of Bailey′s transformation and certain known summations of truncated series, an attempt has been made to establish transformation formulae involving polybasic hypergeometric series.

One-parameter generalizations of Rogers–Ramanujan type identities [PDF]

open access: yes, 2010
Using the recursions satisfied by the polynomials which converge to the right-hand sides of the Rogers–Ramanujan type identities given by Sills (2003) [16] and a determinant method presented in Ismail et al.

Note on Dilogarithm Identities from Nilpotent Double Affine Hecke Algebras

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
Recently Cherednik and Feigin [arXiv:1209.1978] obtained several Rogers-Ramanujan type identities via the nilpotent double affine Hecke algebras (Nil-DAHA).

Tiling Models for Palindromic and n‐Colored Compositions With 1 s and 3 s

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
In this work, we explore compositions of positive integers into parts consisting of 1 and 3 s, highlighting their close connection to the Narayana numbers. We also examine palindromic compositions of this type and introduce arithmetic functions that reflect their structural properties.
