Notes on the structure of the ideal class groups of abelian number fields. (English) Zbl 1084.11060

Euler systems of cyclotomic units and Stickelberger elements introduced by V. A. Kolyvagin [Grothendieck Festschrift 435–483 (1990; Zbl 0742.14017)] and L. C. Washington [Introduction to Cyclotomic Fields. 2nd ed. Graduate Texts in Mathematics. 83. (New York, NY: Springer) (1997; Zbl 0966.11047)] turned out to be an important tool for studying the structure of the ideal class groups of cyclotomic number fields.
In this article, the author derives explicit formulas for certain higher annihilators, and uses them to derive results on the structure of the \(p\)-class groups of cyclotomic number fields of degree not divisible by \(p\).
