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 \ \ \ \ \…
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…
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…
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…
