    An overpartition analogue of the qq-binomial coefficients

    Full text link
    We define an overpartition analogue of Gaussian polynomials (also known as qq-binomial coefficients) as a generating function for the number of overpartitions fitting inside the MΓ—NM \times N rectangle. We call these new polynomials over Gaussian polynomials or over qq-binomial coefficients. We investigate basic properties and applications of over qq-binomial coefficients. In particular, via the recurrences and combinatorial interpretations of over q-binomial coefficients, we prove a Rogers-Ramaujan type partition theorem.Comment: v2: new section added about another way of proving our theorems using q-series identitie

    Theorems, Problems and Conjectures

    Full text link
    These notes are designed to offer some (perhaps new) codicils to related work, a list of problems and conjectures seeking (preferably) combinatorial proofs. The main items are Eulerian polynomials and hook/contents of Young diagram, mostly on the latter. The new additions include items on Frobenius theorem and multi-core partitions; most recently, some problems on (what we call) colored overpartitions. Formulas analogues to or in the spirit of works by Han, Nekrasov-Okounkov and Stanley are distributed throughout. Concluding remarks are provided at the end in hopes of directing the interested researcher, properly.Comment: 14 page

    Some Separable integer partition classes

    Full text link
    Recently, Andrews introduced separable integer partition classes and analyzed some well-known theorems. In this paper, we investigate partitions with parts separated by parity introduced by Andrews with the aid of separable integer partition classes with modulus 22. We also extend separable integer partition classes with modulus 11 to overpartitions, called separable overpartition classes. We study overpartitions and the overpartition analogue of Rogers-Ramanujan identities, which are separable overpartition classes
