Positivity and tails of Jacobi theta series

Nian Hong Zhou

Using elementary -series manipulations, we establish a positivity property for the tails of the Jacobi theta series. Specifically, for integers and , define \[…

Monotonicity of the rank functions for concave compositions

Nian Hong Zhou

A (strongly) concave composition of an integer is a sequence of positive integers that is (strictly) decreasing to a point and then (strictly) increasing thereafter, such that…

Theta functions and transformations of bilateral basic hypergeometric series

Nian Hong Zhou

We establish new transformation formulas involving theta functions and certain bilateral basic hypergeometric series. From these formulas, we construct companion -series for a c…

Restricted divisor functions and half Appell sums in higher-level

Meng-Juan Tian, Nian Hong Zhou

We examine the value distributions of coefficients in certain -series related to half Appell sums in higher-level and the first moment of the Garvan's -rank of partitions. We…

Residue class biases in unrestricted partitions, partitions into distinct parts, and overpartitions

Michael J. Schlosser, Nian Hong Zhou

We prove specific biases in the number of occurrences of parts belonging to two different residue classes and , modulo a fixed non-negative integer , for the sets of unre…

Unimodality and certain bivariate formal Laurent series

Nian Hong Zhou

In this paper, we examine the unimodality and strict unimodality of certain formal bivariate Laurent series with non-negative coefficients. We show that the sets of these formal bi…
