Abstract

Let p be an odd prime number and F a number field. Let K = F ( ζ p ) and Δ = G a l ( K / F ) . Let 𝒮 Δ be the Stickelberger ideal of the group ring Z [ Δ ] defined in the previous paper [8]. As a consequence of a p -integer version of a theorem of McCulloh [15], [16], it follows that F has the Hilbert-Speiser type property for the rings of p -integers of elementary abelian extensions over F of exponent p if and only if the ideal 𝒮 Δ annihilates the p -ideal class group of K . In this paper, we study some properties of the ideal 𝒮 Δ ,and check whether or not a subfield of Q ( ζ p ) satisfies the above property.
