Recently Berndt, Bhargava and Garvan were able to prove all of Ramanujan's results in the notebooks on his theories of elliptic functions to alternative bases. In this paper we show how we used MAPLE to understand, prove and generalize some of Ramanujan's results.

β¦ Synopsis
In his famous paper [11], [12, pp. 23 39], Ramanujan offers several elegant series for 1Γ?. He then remarks, ``There are corresponding theories in which q is replaced by one or other of the functions''
where r=3, 4, or 6 and where 2 F 1 denotes the classical Gaussian hypergeometric function. In the classical theory of elliptic functions, the variable

Let C be a smooth plane quartic curve over a field k and k C be a rational function field of C. We develop a field theory for k C in the following method. Let Ο P be the projection from C to a line l with a center P β 2 . The Ο P induces an extension field k C /k 1 , where k 1 is a maximal rational
Let f (a, b) denote Ramanujan's theta series. In his ``Lost Notebook'', Ramanujan claimed that the ``circular'' summation of n th powers of f satisfies a factorization of the form f (a n , b n ) F n (a n b n ) where F n (q)=1+2nq (n&1)Γ2 + } } } . Moreover, he listed explicit closed formulas for F 2
In the unorganized pages of his second notebook, Ramanujan offers two new theta-function identities that have a form different from other identities found in the literature. Using the theory of modular forms, we prove a general theorem containing Ramanujan's two identities as special cases. 1994 Aca
