A class number problem for imaginary cyclic number fields of 2-power degrees

Number Theory 2025-08-15 v1

Abstract

In 2024, M. K. Ram proved that the class number of an imaginary cyclic quartic number field is never equal to a prime p3(mod4)p\equiv 3\pmod 4. Here we greatly generalize this result to the case of the non-quadratic imaginary cyclic number fields of 22-power degrees and not necessarily prime class numbers.
