A Note on Cubic Modular Equations of Degree Two * M. S. Mahadeva Naika Department of Mathematics, Bangalore University, Central College Campus Bangalore 560 001, Karnataka State, India Received June 23, 2004, Accepted January 14, 2005. Abstract On Page 259 of his second notebook [3], Ramanujan recorded many cubic modular equations of degree 2. In this paper we establish several cubic modular equations of degree 2 akin to those in Ramanujan’s work. As an application of our results, we also establish some new P - Q eta- function identities. Keywords and Phrases: Cubic modular equations, Eta-function identities. Tamsui Oxford Journal of Mathematical Sciences 22(1) (2006) 1-8 Aletheia University 1.
