Quasimodular forms arising from Jacobi's theta function and special symmetric polynomials

Tewodros Amdeberhan, Leonid G. Fel, Ken Ono

Ramanujan derived a sequence of even weight $2 n$ quasimodular forms $U_{2 n} (q)$ from derivatives of Jacobi's weight $3/2$ theta function. Using the generating function for this seq…

Hecke polynomials for the mock modular form arising from the Delta-function

Kevin Gomez, Ken Ono

We consider a mock modular form $M_{I^} (I ¨ )$ that arises naturally from Ramanujan's Delta-function. It is a weight $- 10$ harmonic Maass form whose nonholomorphic part is the "period…
