    Some qq-congruences for homogeneous and quasi-homogeneous multiple qq-harmonic sums

    Full text link
    We show some new Wolstenholme type qq-congruences for some classes of multiple qq-harmonic sums of arbitrary depth with strings of indices composed of ones, twos and threes. Most of these results are qq-extensions of the corresponding congruences for ordinary multiple harmonic sums obtained by the authors in a previous paper. Finally, we pose a conjecture concerning two kinds of cyclic sums of multiple qq-harmonic sums.Comment: This article is based on the previous version, but the results have been reworked and extended substantiall

    Ohno-type identities for multiple harmonic sums

    Full text link
    We establish Ohno-type identities for multiple harmonic (qq-)sums which generalize Hoffman's identity and Bradley's identity. Our result leads to a new proof of the Ohno-type relation for A\mathcal{A}-finite multiple zeta values recently proved by Hirose, Imatomi, Murahara and Saito. As a further application, we give certain sum formulas for A2\mathcal{A}_2- or A3\mathcal{A}_3-finite multiple zeta values.Comment: 14 pages, Some minor correction

    Some series and integrals involving the Riemann zeta function, binomial coefficients and the harmonic numbers. Volume II(a)

    Full text link
    In this series of seven papers, predominantly by means of elementary analysis, we establish a number of identities related to the Riemann zeta function. Whilst this paper is mainly expository, some of the formulae reported in it are believed to be new, and the paper may also be of interest specifically due to the fact that most of the various identities have been derived by elementary methods.Comment: This revised paper contains some corrections and some additional materia
