We study equivariant Iwasawa theory for two-variable abelian extensions of an imaginary quadratic field. One of the main goals of this paper is to describe the Fitting ideals of Iwasawa modules using -adic -functions. We also provide an application to Selmer groups of elliptic curves with complex multiplication.
