They often appear as curves with 3-fold or 6-fold symmetry, playing a key role in the study of Ramanujan-type congruence properties and generating functions, such as theta functions, defined through Eisenstein series. [ 1 , 2 , 3 , 4 , 5 ] Key Aspects of Eisenstein Elliptic Curves Complex Multiplication (CM): These curves have an endomorphism ring strictly larger than \(\mathbb{Z}\), specifically the ful...
