ON SOME NEW MOCK THETA FUNCTIONS
Journal of the Australian Mathematical Society, 2018In 1991, Andrews and Hickerson established a new Bailey pair and combined it with the constant term method to prove some results related to sixth-order mock theta functions. In this paper, we study how this pair gives rise to new mock theta functions in terms of Appell–Lerch sums.

New mock theta functions and formulas for basic hypergeometric series
Proceedings of the Edinburgh Mathematical Society, 2023In recent years, mock theta functions in the modern sense have received great attention to seek examples of q-hypergeometric series and find their alternative representations.

Transcendental formulas for the coefficients of Ramanujan’s mock theta functions
Research in Number TheoryRamanujan’s 1920 last letter to Hardy contains seventeen examples of mock theta functions which he organized into three “orders.” The most famous of these is the third-order function f(q) which has received the most attention of any individual mock theta

In this paper, employing some identities due to Newman, we present a new method for discovering infinite families of congruences and strange congruences for c ( n ) {c(n)} which is defined by ∑ n = 0 ∞ c ( n ) q n = ∏ k = 1 ∞ ( 1 - q k ) r ( 1 ...

Mock Theta Functions and Mock Modular Forms
2012In 1920, three months before his untimely death, Ramanujan hastily described the beginnings of a new theory he called “mock theta functions.” In 2001, Zwegers in his doctoral thesis, discovered the relation between non-holomorphic modular forms, indefinite theta series, and “mock theta functions.” We briefly describe this development in this chapter.

Fifth Order Mock Theta Functions: Proof of the Mock Theta Conjectures
2018In Chapter 3, Section 3.1, we defined Ramanujan’s ten fifth order mock theta functions, and in Chapter 5 we stated the ten mock theta conjectures. The point of the latter chapter was to reveal that the conjectures could be separated into two groups of 5 each and that the conjectures within each group are equivalent.

Some identities on the second order mock theta functions
The Ramanujan journalRecently, Nath and Das investigated congruence properties for the second order mock theta function B(q). In their paper, they asked for analytic proofs of three identities on the second order mock theta functions A(q), B(q) and μ2(q)\documentclass[12pt ...

Some Eighth Order Mock Theta Functions
Journal of the London Mathematical Society, 2000Summary: A method is developed for obtaining Ramanujan's mock theta functions from ordinary theta functions by performing certain operations on their \(q\)-series expansions. The method is then used to construct several new mock theta functions, including the first ones of eighth order.

The Quarterly Journal of Mathematics, 2011
The purpose of this paper is to use a general class of indefinite theta functions to explain and generalize an example of a Maass waveform that was constructed by Cohen from two functions σ and σ*, studied by Andrews, Dyson and Hickerson. For this, we construct certain functions attached to an indefinite binary quadratic form and show that they are ...

THE COEFFICIENTS OF THE ω(q) MOCK THETA FUNCTION
International Journal of Number Theory, 2008In 1920, Ramanujan wrote to Hardy about his discovery of the mock theta functions. In the years since, there has been much work in understanding the transformation properties and asymptotic nature of these functions. Recently, Zwegers proved a relationship between mock theta functions and vector-valued modular forms, and Bringmann and Ono used the ...
