Abstract:

We determine all the simplest cubic fields whose ideal class groups have exponent dividing $3$, thus generalizing the determination by G. Lettl of all the simplest cubic fields with class number $1$ and the determination by D. Byeon of all all the simplest cubic fields with class number $3$. We prove that there are $23$ simplest cubic fields with ideal class groups of exponent $3$ (and $8$ simplest cubic fields with ideal class groups of exponent $1$, i.e. with class number one).
