In this paper, we study third-order modular ordinary differential equations (MODE for short) of the following form ′′′ + ₂()′ + ₃() = 0, ∈ ℍ = { ∈ ℂ | Im > 0}, where ₂() and ₃() − 1/2′₂() are meromorphic modular forms on SL(2, ℤ) of weight 4 and 6, respectively. We show that any quasimodular for...
