Modular elliptic curves over real abelian fields and the generalized Fermat equation x2โ+ y2m= zp
Let K be a real abelian field of odd class number in which 5 is unramified.Let S 5 be the set of places of K above 5.Suppose for every nonempty proper subset S โ S 5 there is a totally positive unit u โ O K such that qโS Norm โฆ
