Ishii, Hidenori The non-existence of abelian varieties of type (K) with everywhere good reduction over imaginary quadratic fields. (English) Zbl 0705.14040 Jap. J. Math., New Ser. 15, No. 1, 213-219 (1989). The author generalizes his result of non-existence of elliptic curves with good reduction defined over an imaginary quadratic field k to the case of abelian varieties of some type. Let K be a totally real algebraic number field. Let (A,\(\theta\)) be an abelian variety of type \((K)\) defined over k, in a usual sense. Further we call (A,\(\theta\)) an abelian variety of type \((K)\) over \({\mathfrak o}_ k\), the ring of all integers in k, when the Néron model of A over \({\mathfrak o}_ k\) is an abelian scheme over \({\mathfrak o}_ k.\) Then the main theorem asserts that there is no abelian variety of type \((K)\) over \({\mathfrak o}_ k\) when the class number of k is prime to 6 and there exists an element of \({\mathfrak o}_ K\), the ring of all integers in K, of norm 3.
