Exponent of class group of certain imaginary quadratic fields /
Let $n>1$ be an odd integer. We prove that there are infinitely many imaginary quadratic fields of the form $\mathbb{Q} \bigl(\sqrt{x^2-2y^n} \bigr)$ whose ideal class group has an element of order $n$. This family gives a counterexample to a conjecture by H. Wada (1970) on the structure of ideal...
