A Family of Theta-Function Identities Based upon Combinatorial Partition Identities Related to Jacobi’s Triple-Product Identity

open access: yesMathematics, 2020
The authors establish a set of six new theta-function identities involving multivariable R-functions which are based upon a number of q-product identities and Jacobi’s celebrated triple-product identity.

Partition identities arising from theta function identities [PDF]

open access: yesActa Mathematica Sinica, English Series, 2008
This paper is devoted to a study of the combinatorics of identities that generally have the form \[ f(q) + f(-q) = g(q) \] or \[ f(q) - f(-q) = qh(q), \] where \(f(q)\) is some infinite product which is essentially a modular function. The motivation is one such identity of \textit{H. M. Farkas} and \textit{I. Kra} [Contemp. Math.

Partition-theoretic interpretations of some q-series identities of Ramanujan

open access: yesKuwait Journal of Science, 2021
Ramanujan's lost notebook contains several $q$-series identities  and some of them have theta-function representations. We give partition-theoretic interpretations of some of these identities  and prove Ramanujan-type congruences for certain partition ...

On relationships between q-products identities, Ralpha, Rbeta and Rm functions related to Jacobi's triple-product identity [PDF]

open access: yesMathematica Moravica, 2020
The authors establish a set of two new relationships involving q-product identities, Ralpha, Rbeta, and Rm (m = 1, 2, 3, . . .) functions; and answer a open question of Srivastava et al. [18].

Some Special Integer Partitions Generated by a Family of Functions

open access: yesTrends in Computational and Applied Mathematics, 2023
  In this work, inspired by Ramanujan’s fifth order Mock Theta function f1(q), we define a collection of functions and look at them as generating functions for partitions of some integer n containing at least m parts equal to each one of the numbers from

Theta function identities involving fourth power [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
On page 241 of his Second Notebook, Ramanujan recorded one of his theta function identity, which involves the ratio of the fourth power of theta functions with respect to ψ(q). In this article, we give a new proof for this theta function identity.

On certain identities in theta functions [PDF]

open access: yesTransactions of the American Mathematical Society, 1930
1. The purpose of this paper is to obtain certain identities in Jacobi's theta functions by a new method. This method may be outlined as follows. We consider two sets of elements S and Si, conceptually distinct, such that the elements of S are in one-to-one correspondence with the elements of S1.
