abstract = {In this chapter we discuss several alternatives and extensions to the definition of Euler systems we gave in Chapter 2.It is tempting to remove from the definition of an Euler system the requirement that the fieldK(over whose subfields the Euler system classes are defined) contain a Zp-extension ofK. After all, the proofs of the Theorems of §2.2 only use the derivative classesK[K,τ,M]and not theK[F,τ,M]for larger extensionsFofKinK∞. However, our proofs of the properties of the derivative classesK[K,τ,M]very much used the fact that the Euler system class},
