Quasimodular forms that detect primes are Eisenstein

Jan-Willem van Ittersum, Lukas Mauth, Ken Ono +1

MacMahon's partition functions and their extensions provide equations that identify prime numbers as solutions. These results depend on the theory of (mixed weight) quasimodular fo…

Pentagonal number recurrence relations for

Kevin Gomez, Ken Ono, Hasan Saad +1

We revisit Euler's partition function recurrence, which asserts, for integers that $$ p(n)=p(n-1)+p(n-2)-p(n-5)-p(n-7)+\dots = \sum_{k\in \mathbb{Z}\setminus \{0\}} (-1)…

Traces of partition Eisenstein series

Tewodros Amdeberhan, Michael Griffin, Ken Ono +1

We study "partition Eisenstein series", extensions of the Eisenstein series defined by $$λ=(1^{m_1}, 2^{m_2},\dots, k^{m_k}) \vdash k \ \ \ \ \ \longmapsto \ \ \ \ \ G…

Certain infinite products in terms of MacMahon type series

Seokho Jin, Badri Vishal Pandey, Ajit Singh

Recently, Ono and the third author discovered that the reciprocals of the theta series and have infinitely many closed formulas…

Derivatives of theta functions as Traces of Partition Eisenstein series

Tewodros Amdeberhan, Ken Ono, Ajit Singh

In his "lost notebook'', Ramanujan used iterated derivatives of two theta functions to define sequences of -series and that he claimed to be quas…

Arithmetic properties for generalized cubic partitions and overpartitions modulo a prime

Tewodros Amdeberhan, James A. Sellers, Ajit Singh

A cubic partition is an integer partition wherein the even parts can appear in two colors. In this paper, we introduce the notion of generalized cubic partitions and prove a number…

Distribution of hooks in self-conjugate partitions

William Craig, Ken Ono, Ajit Singh

We confirm the speculation that the distribution of -hooks among unrestricted integer partitions essentially descends to self-conjugate partitions. Namely, we prove that the num…

Generalized cubic partitions

Tewodros Amdeberhan, Ajit Singh

A cubic partition consists of partition pairs such that where involves only even integers but no restriction is placed on . This paper in…

Remarks on MacMahon's -series

Ken Ono, Ajit Singh

In his important 1920 paper on partitions, MacMahon defined the partition generating functions \begin{align*} A_k(q)=\sum_{n=1}^{\infty}\mathfrak{m}(k;n)q^n&:=\sum_{0< s_1<s_2<\cdo…

Hook lengths in self-conjugate partitions

Tewodros Amdeberhan, George E. Andrews, Ken Ono +1

In 2010, G.-N. Han obtained the generating function for the number of size hooks among integer partitions. Here we obtain these generating functions for self-conjugate partitio…

MacMahon's sums-of-divisors and allied -series

Tewodros Amdeberhan, Ken Ono, Ajit Singh

Here we investigate the -series \begin{align*} \mathcal{U}_a(q)&=\sum_{n=0}^{\infty} MO(a;n)q^n&:=\sum_{0< k_1<k_2<\cdots<k_a} \frac{q^{k_1+k_2+\cdots+k_a}}{(1-q^{k_1})^2(1-q^{k…
